WARNING
Radio Frequency Radiation Hazard
The radar antenna emits electromagnetic radio frequency (RF) energy which can be harmful,
particularly to your eyes. Never look directly into the antenna aperture from a close distance
while the radar ius in operation or eexpose yourself to the transmitting antenna at a close
distance. Distances at which RF radiation level of 100, 50 and 10 W/m 2 are given in the table
below.
Note: If the antenna unit is installed at a close distance in front of the wheel house, your
administration may require halt of transmission within a certain sector of antenna revolution.
This is possible. Ask your FURUNO representive or dealer to provide this feature.

SAFETY INSTRUCTIONS
WARNING
ELECTRICAL SHOCK HAZARD
WARNING
Use the proper fuse.
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Turn off the radar power
switch before servicing the
antenna unit. Post a warning sign near the switch
indicating it should not be
turned on while the antenna
unit is being serviced.
Prevent the potential risk of
being struck by the rotating
antenna and exposure to
RF radiation hazard.
Wear a safety belt and hard
hat when working on the
antenna unit.
Serious injury or death can
result if someone falls from
the radar antenna mast.
Use of a wrong fuse can result in damage
to the equipment or cause fire.
Keep heater away from equipment.
Heat can alter equipment shape and melt
the power cord, which can cause fire or
electrical shock.
Do not place liquid-filled containers
near the equipment.
Fire or electrical shock can result if a liquid
spills into the equipment.
Do not operate the equipment with wet
hands.
Electrical shock can result.
Before servicing the radar, turn off
the appropriate external breaker.
Power is not removed from the radar simply
by turning off its power switch.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Immediately turn off the power at the
ship's mains switchboard if water
leaks into the equipment or the equipment is emitting smoke or fire.
Continued use can cause fatal damage to
the equipment.

SAFETY INSTRUCTIONS
CAUTION
WARNING
No one navigational aid should be relied
upon for the safety of vessel and crew.
The navigator has the responsibility to
check all aids available to confirm
position. Electronic aids are not
a substitute for basic navigational
principles and common sense.
• This TT automatically tracks
automatically or manually acquired radar
targets and calculates their courses and
speeds, indicating them by vectors. Since
the data generated by the auto plotter
are based on what radar targets are
selected, the radar must always be
optimally tuned for use with the auto
plotter, to ensure required targets will not
be lost or unwanted targets such as sea
returns and noise will not be acquired
and tracked.
• A target does not always mean a landmass, reef, ships or other surface vessels
but can imply returns from sea surface
and clutter. As the level of clutter changes
with environment, the operator should
properly adjust the A/C SEA, A/C RAIN
and GAIN controls to be sure target
echoes are not eliminated from the
radar screen.
The plotting accuracy and response of
this TT meets IMO standards.
Tracking accuracy is affected by the
following:
• Tracking accuracy is affected by course
change. One to two minutes is required to
restore vectors to full accuracy after an
abrupt course change. (The actual
amount depends on gyrocompass
specifications.)
• The amount of tracking delay is inversely
proportional to the relative speed of the
target. Delay is on the order of 15—30
seconds for high relative speed; 30—60
seconds for low relative speed.
• Display accuracy is affected by the
following:
- Echo intensity
- Radar transmission pulsewidth
- Radar bearing error
- Gyrocompass error
- Course change (own ship and target)
The data generated by TT, AIS and
video plotter are intended for
reference only.
Refer to official nautical charts for
detailed and up-to-date information.
WARNING LABEL
Warning labels are attached to the
equipment. Do not remove any label.
If a label is missing or damaged,
contact a FURUNO agent or dealer
about replacement.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.
WARNING
Radiation hazard. Only qualified
personnel should work inside scanner.
Confirm that TX has stopped before
opening scanner.

RADAR OPERATION
1.1
Turning on the Power
The [POWER] switch ( ) is located at the left corner of the control unit. Open the
POWER switch cover and press the switch to turn on the radar system. To turn
off the radar, press the switch again. The screen shows the bearing scale and
digital timer approximately 30 seconds after power-on. The timer counts down
three minutes of warm-up time. During this period the magnetron (transmitter
tube) is warmed for transmission. When the timer has reached 0:00, the
indication "ST-BY" appears at the screen center, meaning the radar is now ready
to transmit pulses.
In the stand-by condition, markers, rings, map, charts, etc. are not shown.
Further, TT and AIS are not shown.
In the warm-up and stand-by conditions, ON TIME and TX TIME count in hours
and tenths of hour appear at the screen center.
Note 1: Do not turn the power on directly after it has been turned off. Wait
several seconds before you reapply the power, to be sure the radar
starts up properly.
Note 2: Parameters set on the menus are stored in a non-volatile memory (flash
memory), and are preserved when the power is turned off.
1.2
Transmitter ON
After the power is turned on and the magnetron has warmed up, ST-BY appears
at the screen center, meaning the radar is ready to transmit radar pulses. You
may transmit by pressing the [STBY/TX] key on the full keyboard, or use the
trackball to select the TX STBY box at the bottom left corner of the display then
push the left button (above the trackball). The label at the left-hand side of the
guidance box at the bottom right corner of the screen changes from TX to STBY.

1. RADAR OPERATION
The radar is initially set to previously used range and pulse length. Other
settings such as brilliance levels, VRMs, EBLs and menu option selections are
also set to previous settings.
The [STBY/TX] key (or TX STBY box) toggles the radar between STBY and
TRANSMIT status. The antenna stops in stand-by and rotates in transmit. The
magnetron ages with time resulting in a reduction of output power. Therefore, it
is highly recommended that the radar be set to stand-by when not used for an
extended period of time.
How to stop antenna rotation
Antenna rotation can be stopped. One method is to turn off the antenna switch
on the radar. The other method is to stop rotation from the menu. For how to
stop rotation from the menu, see the installation manual.
Picture freeze
When the picture freezes the picture is not updated. 30 seconds after the picture
freezes, the buzzer sounds, the [ALARM ACK] key blinks and the alarm contact
signal is output. Reset the power to restore normal operation.
Quick start
Provided that the radar was once in use with the transmitter tube (magnetron)
still warm, you can turn the radar into TRANSMIT condition without three
minutes of warm-up. If the [POWER] switch was turned off by mistake or the like
and you wish to restart the radar promptly, turn on the [POWER] switch not later
than 10 seconds after power-off.
Echo area
The echo display area for the B, C and W types is available in three
configurations: round, wide, and full screen. You can select a configuration with 7
ECHO AREA on the ECHO menu.

Operation by the On-Screen Boxes
All radar functions can be accessed by using the trackball alone. This is done by
choosing the appropriate on-screen box with the trackball and operating the
trackball module to select item and option. (See section 1.9 for location of all
on-screen boxes.) On-screen boxes come in two varieties: Function selection
and function selection w/pop-up menu. On-screen boxes of the latter type have
"►" at the right side of their boxes, as in the MARK box shown below.
To operate the radar using on-screen boxes, do the following:
1. Use the trackball to place the trackball marker inside the box desired.
Note: The trackball marker changes its configuration according to its location.
It is an arrow when placed outside the effective display and a cursor
(+) when inside the effective display. See the illustration on the next
page for further details.
For example, select the MARK box, which is at the bottom left corner.

When a box is correctly selected, its color changes from green to orange and
the guidance box at the bottom right corner shows operational guidance. The
operational guidance shows the function of the left and right buttons, with a
diagonal line separating the information. For the MARK box, for example, the
operational guidance is "MARK SELECT / MARK MENU." In this case you
would push the left button to select a mark or push the right button to open
the MARK menu.

To choose boxes successively, push the wheel
when the guidance box reads as above.
Then, the nearest box is selected and marked
with the double-ended arrow ( ) and the
guidance box reads
"JUMP FORWARD / JUMP BACKWARD."
Hit the left button to go to the box below or
adjacent to the currently selected box or hit
the right button to go to the box above or
adjacent to the currently selected box.
Continue pushing a button to choose boxes
successively. This is convenient for operation
under heavy pitching and rolling. To cancel this
feature, push the wheel when the guidance box
reads as above.
Guidance box reads
"TARGET DATA & ACQ / CURSOR MENU."
In this condition you may access cursor-operated
functions, by hitting the left button for direct
selection of function or the right button to choose
desired functions from the CURSOR menu. For
further details about the CURSOR menu,

2. Push the left button (or roll the scrollwheel depending on the box) until the
desired option is displayed in the box.
Note: When you selected an on-screen box’s option by rolling the
scrollwheel, the box and its contents turn light-blue. This simply
indicates that the selected setting is different from the currently active
setting. To change the setting, push the scrollwheel or the left button. If
neither the scrollwheel nor the left button is pushed within about 30
seconds after operating the scrollwheel, the previous setting is
automatically restored.

The course-up mode is an azimuth-stabilized display in which a line connecting
the center with the top of the display indicates own ship’s intended course
(namely, own ship’s previous heading just before this mode has been selected).
Target pips are painted at their measured distances and in their directions
relative to the intended course, which is maintained at the 0-degree position. The
heading line moves in accordance with ship’s yawing and course change. This
mode is useful to avoid smearing of picture during course change.

1. RADAR OPERATION
Head-up TB (True Bearing) mode
Radar echoes are shown in the same way as in the head-up mode. The
difference from normal head-up presentation lies in the orientation of the bearing
scale. The bearing scale is heading sensor stabilized. That is, it rotates in
accordance with the heading sensor signal, enabling you to know own ship’s
heading at a glance.
This mode is available when the radar is interfaced with a gyrocompass.
If the gyrocompass fails, the bearing scale returns to the state of head-up mode.
North-up mode
The north-up mode paints target pips at their measured distances and in their
true (heading sensor) directions from own ship, north bearing maintained at the
top of the screen. The heading line changes its direction according to the ship’s
heading. Requires heading signal.
If the compass fails, the presentation mode changes to head-up and the north
marker disappears. Also, the HDG indication shows ***.*°. And the message
HDG SIG MISSING appears in red at the lower-right corner of the screen.

1. RADAR OPERATION
True motion mode
Own ship and other moving objects move in accordance with their true courses
and speed. In ground stabilized TM, all fixed targets, such as landmasses,
appear as stationary echoes. In the sea stabilized TM without set and drift inputs,
the landmass can move on the screen. Note that true motion is not available on
the 72 nm (non-IMO type only) or 96 nm range scale. If COG and SOG (both
over the ground) are not available on TM mode, enter the set (tide direction) and
drift (tide speed) manually referring to the Tide Table.
When own ship reaches a point corresponding to 50% of the radius of the
display, own ship position is automatically reset to a point of 75% radius opposite
to the extension of the heading line passing through the display center. You may
also reset the own ship symbol manually by pressing the [CU/TM RESET] key,
or left-clicking the CU/TM RESET box at the bottom right corner of the display.
If the heading sensor fails, the mode is changed to the head-up and the north
marker disappears. The HDG readout shows ***.*° and the message HDG SIG
MISSING appears in red at the lower-right corner of the screen.
Note: A part of the bearing scale is drawn differently depending on antenna
reference position.
ANT: Bearing scale interval is different when display is offcentered.
CONN: A part of the bearing scale is not displayed if the conning position is not
within the radar display area.

Adjusting the Sensitivity
The gain control adjusts the sensitivity of the receiver.
The proper setting is such that the background noise is just visible on the screen.
If you set up for too little sensitivity, weak echoes may be missed. On the other
hand excessive sensitivity yields too much background noise; strong targets may
be missed because of the poor contrast between desired echoes and the
background noise on the display.
To adjust receiver sensitivity, adjust the gain control so background noise is just
visible on the screen.

Reducing Sea Clutter
Echoes from waves cover the central part of the display with random signals
known as sea clutter. The higher the waves, and the higher the antenna above
the water, the further the clutter extends. When sea clutter masks the picture,
reduce it by the A/C SEA control, either manually or automatically.
Note 1: When both sea clutter and rain clutter are reduced, the sensitivity is
decreased more than when only one is adjusted. For that reason adjust
them carefully.
Note 2: The echo average (see 1.27) is useful for reducing reflections from the
sea surface. However, high-speed targets are harder to detect than
stationary ones when the echo average is active.

1.17.2
Automatic reduction of sea clutter
Auto A/C SEA allows for fine tuning of the A/C SEA circuit, within ±20 dB.
Accordingly, with the bar reading set to 100, gain is not lowered to minimum as
with manual A/C SEA on close-in ranges. Further, the auto A/C SEA level is low
because the average value of the original input echo is low in areas where there
are no sea surface reflections. For example, when the ship is alongside a quay
and the radar picture shows echoes from both land and sea, you can observe
the size of the echoes because the STC curve changes with the size of the
echoes.
Note: The auto A/C function can erase weak target echoes. Adjust the control
carefully, watching the display.
By keyboard
1. Select SEA AUTO following the procedure in section 1.17.1.
2. While observing the A/C SEA level indicator, adjust the A/C SEA with the [A/C

1.17.3
Manual reduction of sea clutter
The A/C SEA control reduces the amplification of echoes at short ranges (where
clutter is the greatest) and progressively increases amplification as the range
increases, so amplification will be normal at those ranges where there is no sea
clutter.
The proper setting of the A/C SEA should be such that the clutter is broken up
into small dots, and small targets become distinguishable. If the setting is set too
low, targets will be hidden in the clutter, while if the setting is too high, both sea
clutter and targets will disappear from the display. In most cases adjust the
control until clutter has disappeared to leeward, but a little is still visible
windward. Be careful not to remove all sea clutter, because you may erase weak
echoes. Further, the possibility of losing weak echoes is greater when you use
both A/C SEA and A/C RAIN to reduce clutter.

Reducing Rain Clutter
Use the AUTO RAIN and A/C RAIN to reduced rain clutter. AUTO RAIN reduces
rain clutter in the picture and A/C RAIN reduces clutter picked up by the antenna.
Note 1: When both sea clutter and rain clutter are reduced the sensitivity is
decreased more than when only one is adjusted. For that reason adjust
them carefully.
Note 2: The echo average (see 1.27) is useful for reducing reflections from the
sea surface. However, high-speed targets are harder to detect than
stationary ones when the echo average is active.
1.18.1
Automatic reduction of rain clutter
Left-click the AUTO RAIN indication at the left side of the screen to select AUTO
RAIN setting desired. The higher the number, the greater the degree of rain
clutter reduction. OFF turns off the AUTO RAIN feature.
Note: AUTO RAIN can also be controlled from the PICTURE box.
1.18.2
Manual reduction of rain clutter
The vertical beam width of
the antenna is designed to
see surface targets even
when the ship is rolling.
However, by this design
the unit will also detect rain
clutter (rain, snow, or hail)
in the same manner as
normal targets.
Unwanted echoes are
displayed
A/C RAIN control adjusted.
The A/C RAIN control adjusts the receiver sensitivity as the A/C SEA control
does but rather in a longer time period (longer range). The higher the setting the
greater the anti-clutter effect. When echoes from precipitation mask solid targets,
adjust the A/C RAIN control to split up these unwanted echoes into a speckled
pattern, making recognition of solid targets easier. Be careful remove all rain
clutter, because you can erase weak echoes. Further, the possibility of losing
weak echoes is greater when you use both A/C RAIN and A/C SEA to reduce
clutter.

Measuring Range
The range to a target may be measured three ways: with the fixed range rings,
with the cursor, or with the VRM.
Use the fixed range rings to get an estimate of the range to a target. The rings
are the concentric solid circles on the display. The number of rings is
automatically set by the current range scale. The distance between the rings is
the range ring interval, and the current interval appears at the upper-left position
on the screen. To measure the range to a target with the range rings, count the
number of rings between the center of the display and the target. Check the
range ring interval and estimate the distance of the echo from the inner edge of
the nearest ring.

Measuring Bearing
Use the Electronic Bearing Lines (EBLs) to take bearings of targets. There are
two EBLs, No. 1 and No. 2. Each EBL is a straight dashed line extending out
from the own ship position up to the circumference of the radar picture. The two
EBLs can be distinguished from each other by the different lengths of their
dashes; the dashes on the No. 2 EBL are longer.
Each EBL carries a range marker, or a short line crossing the EBL at right angles.
Its distance from the EBL origin is indicated at the VRM readout whether or not
the corresponding VRM is displayed. The range marker changes its position
along the EBL with the rotation of the VRM control. To operate this marker, rotate
the VRM rotary control on the full keyboard, or put the cursor in the applicable

Collision Assessment by Offset EBL
The origin of the EBL can be placed anywhere with the trackball to enable
measurement of range and bearing between any targets. This function is also
useful for assessment of the potential risk of collision. It is possible to read CPA
(Closest Point of Approach) by using a VRM as shown in (a) in the illustration on
the next page. If the EBL passes through the sweep origin (own ship) as shown
in (b) in the illustration on the next page, the target ship is on a collision course.
1.21.1
How to assess risk of collision by the offset EBL
By keyboard
1. Press the [EBL ON] key to display or activate an EBL (No. 1 or No. 2).
2. Put the cursor (+) on a target appearing as threatening (A in the illustrated
example on the next page) by operating the trackball.
3. Press the [EBL OFFSET] key, and the origin of the active EBL shifts to the
cursor position. Press the [EBL OFFSET key] again to anchor the EBL origin.
4. After waiting for a few minutes (at least 3 minutes), operate the EBL rotary
control until the EBL bisects the target at the new position (A'). The EBL
readout shows the target ship's course, which may be true or relative
depending on the EBL bearing reference setting.
Note: If relative motion is selected, it is also possible to read CPA by using a
VRM as shown in left-hand figure at the top of the next page. If the
EBL passes through the sweep origin (own ship) as illustrated in the
right-hand figure at the top of then next page, the target ship is on a
collision course.
5. To return the EBL origin to the own ship's position, press the [EBL OFFSET]
key twice.
By trackball
1. Display an EBL, following steps 1-3 in "By trackball" in section 1.20.1.
2. With the cursor inside the effective display area, push the left button, roll the
scrollwheel to show "EBL OFFSET / EXIT" in the guidance box then push the
left button.
3. Use the trackball to place the offset EBL on a target appearing as threatening
(A in the illustrated example on the next page) then push the left button to
anchor the EBL origin.
4. After waiting for a few minutes (at least 3 minutes), operate the EBL used in
step 1 until it bisects the target at the new position (A'). The EBL readout
shows the target ship's course, which may be true or relative depending on
the EBL bearing reference setting.
To return the EBL origin to the screen center, show "EBL OFFSET / EXIT" in the
guidance window then push the left button.

Target Alarm
The target alarm serves to alert the navigator to targets (ships, landmasses, etc.)
entering a specific area, with audiovisual alarms.
CAUTION
• The alarm should not be relied upon as
the sole means for detecting possible
collision situations.
• A/C SEA, A/C RAIN and GAIN controls
should be properly adjusted to be sure
the alarm system does not overlook
target echoes.
The target alarm zone has a fixed width of 0.5 nm in the radial direction (depth)
and is adjustable from 3.0 to 6.0 nm (guard zone 1) and any distance (guard
zone 2). On the Non-IMO radar the boundaries can be set at any distance. On
any radar type the sector of the zone can be set from 0 to 360 degrees in any
direction.
1.23.1
How to set a target alarm
The procedure below shows how to set a target alarm using the figure below as
an example.

Off-Centering the Display
Own ship position, or sweep origin, can be displaced to expand the view field
without switching to a larger range scale. The sweep origin can be off-centered
to the cursor position, but not more than 75% of the range in use; if the cursor is
set beyond 75% of the range scale, the sweep origin will be off-centered to the
point of 75% of the limit.
This feature is not available on the 96 nm range or in the true motion mode.
If the conning position is outside the effective radar display, some parts of the
bearing scale are not shown. For details, see section 1.50.
To off-center the radar picture, do the following:
By keyboard
1. Use the trackball to put the cursor at a position where you wish to move the
sweep origin.
2. Press the [OFF CENTER] key. Then, the sweep origin is off-centered to the
cursor position.
3. To cancel off-centering, press the [OFF CENTER] key again.

4. To cancel the off-center function, push the left button when the guidance box
reads "OFF CENTER / EXIT."
Note: When the conditions shown below are met, offcenter cannot be cancelled.
This is because the radar antenna position is located at a position greater than
75% of the effective radar display.
- Own ship marker is large
- The distance between antenna position and conning position is large
- Short-distance display range.
To cancel the offcenter first select a larger range then cancel the offcenter.

Interference Rejector
Mutual radar interference may occur in the vicinity of another shipborne radar
operating in the same frequency band. It is seen on the screen as a number of
bright spikes either in irregular patterns or in the form of usually curved
spoke-like dotted lines extending from the center to the edge of the picture.
Activating the interference rejector circuit can reduce this type of interference.
The interference rejector is a kind of signal correlation circuit. It compares the
received signals over successive transmissions and reduces randomly occurring
signals. There are three levels of interference rejection depending on the
number of transmissions that are correlated.
Interference
To adjust the interference rejector, left-click IR indication at the left side of the
screen to select rejection level. "3" provides the highest degree of reduction.
Note: The interference rejector can also be adjusted from the PICTURE box.
1.26
Echo Stretch
The echo stretch feature enlarges targets in the range and bearing directions to
make them easier to see, and it is available on any range. There are three types
of echo stretch, 1, 2 and 3, and the higher the number the greater the amount of
stretch.
Note: The echo stretch magnifies not only small target pips but also returns
(clutter) from sea surface, rain and radar interference. For this reason,
make sure these types of interference have been sufficiently reduced
before activating the echo stretch.
To set echo stretch, left-click the ES indication at the left side of the display.
Note: Echo stretch can also be adjusted from the PICTURE box.

1. RADAR OPERATION
1.27
Echo Averaging
The echo averaging feature effectively reduces sea clutter. Echoes received
from stable targets such as ships appear on the screen at almost the same
position every rotation of the antenna. On the other hand, unstable echoes such
as sea clutter appear at random positions.
To distinguish real target echoes from sea clutter, echoes are averaged over
successive picture frames. If an echo is solid and stable over successive frames,
it is presented in its normal intensity. Sea clutter is averaged over successive
scans and its brilliance reduced, making it easier to discriminate real targets
from sea clutter.
Echo averaging uses scan-to-scan signal correlation technique based on the
true motion over the ground of each target. Thus, small stationary targets such
as buoys will be shown while reducing random echoes such as sea clutter. True
echo averaging is not however effective for picking up small targets running at
high speeds over the ground.
Note 1: With echo average active it is harder to detect high-speed targets than
stationary ones.
Note 2: Do not use the echo averaging function under heavy pitching and
rolling; loss of targets can result.
Note 3: Echo averaging can be used without a heading sensor. For further
details, contact your dealer.
Note 4: Echo averaging requires heading, position and speed data.
Before using the echo averaging function, reduce sea clutter with the A/C SEA
control. Leave a little sea clutter on the screen so as not to erase weak targets.
Then, do as follows:
Left-click the EAV indication at the left side of the display.
OFF:
1, 2:
3:
Echo averaging OFF
Detects targets hidden in sea clutter. "2" is more effective than "1" in
detecting targets hidden in strong sea clutter. However, "1" is more
effective than "2" in displaying high-speed targets. Select the setting
best suited to current conditions. For effective monitoring of
high-speed craft, you should use "2" together with Wiper.
Stably displays unstable targets; distinguishes high-speed craft from
sea clutter.
Note: Echo averaging can also be adjusted from the PICTURE box.

Automatic Picture Setup According to
Navigation Purpose
Every time your navigating environment or task changes, you must adjust the
radar, which can be a nuisance in a busy situation. Instead of changing radar
settings case by case, it is possible to assign the function keys to provide
optimum settings for often encountered situations.
The radar's internal computer offers several picture setup options to be assigned
to each function key for your specific navigating requirements. For instance, one
of the functions is assigned the ship detecting function and labeled SHIP on the
on the PICTURE box. By choosing SHIP, the radar will be instantly set for
optimum detection of ships.
Four user-programmable setups are also provided (labeled
PICTURE1-PICTURE4), so that you may have the radar automatically adjusted
to those conditions that are not covered by the provided setup options.
Below are the preset picture setup options provided with this radar.

Optimum setting for detecting

Each picture setup option defines a combination of several radar settings for
achieving optimum setup for a particular navigating situation. Those involved are
interference rejector, echo stretch, echo average, noise rejector, automatic
anti-sea and anti-rain clutters, video contrast, and pulselength and sea and radar
conditions.
Adjusting these features from the PICTURE menu changes the original function
key settings. To restore the original settings for a particular picture setup option,
it is necessary to select the default setting. For this reason, we recommended
that you use the user-programmable function sets when frequent adjustment of
the radar picture is necessary.

Reference Position
The reference position for measurements (range, bearing, etc.) and markers
(heading line, stern mark, etc.) can be antenna position or consistent common
reference point (CCRP), which is a location on own ship to which all horizontal
measurements, for example range, bearing, relative course, relative speed,
closest point of approach (CPA) or time to closest point of approach (TCPA), are
normally referenced.
To select reference position, right-click the REF POINT indication at the top of
the screen to select ANT or CCRP as applicable.
The position of the own ship marker changes according to reference position as
shown below. If the CCRP is positioned outside of the effective display area, the
bearing scale is indicated with the appropriate reduced detail.

RADAR OBSERVATION
2.1
General
2.1.1
Minimum and maximum ranges
Minimum range
The minimum range is defined by the shortest distance at which, using a scale of
1.5 or 0.75 nm, a target having an echoing area of 10 m2 is still shown separate
from the point representing the antenna position.
It is mainly dependent on the pulselength, antenna height, and signal processing
such as main bang reduction and digital quantization. It is a good practice to use
a shorter range scale as far as it gives favorable definition or clarity of picture.
The IMO Resolution MSC.192(79) requires the minimum range to be less than
40 m, respectively. This series of radars satisfy this requirement.
Maximum range
The maximum detecting range of the radar, Rmax, varies considerably
depending on several factors such as the height of the antenna above the
waterline, the height of the target above the sea, the size, shape and material of
the target, and the atmospheric conditions.
Under normal atmospheric conditions, the maximum range is equal to the radar
horizon or a little shorter. The radar horizon is longer than the optical one by
about 6% because of the diffraction property of the radar signal. The Rmax is
given in the following equation.
R max = 2.2 x ( h1 + h2 )
where Rmax: radar horizon (nautical miles)
h1: antenna height (m)
h2 : target height (m)
Radar horizon
Optical horizon
For example, if the height of the antenna above the waterline is 9 meters and the
height of the target is 16 meters, the maximum radar range is;
R max= 2.2 x ( 9 + 16 ) = 2.2 x (3 + 4) = 15.4 nm
It should be noted that the detection range is reduced by precipitation (which
absorbs the radar signal).
2-1
2. RADAR OBSERVATION
X-band and S-band
In fair weather, the equation on the previous page does not give a significant
difference between X- and S-band radars. However, in heavy precipitation
condition, an S-band radar would have better detection than an X-band radar.
Radar resolution
There are two important factors in radar resolution (discrimination): bearing
resolution and range resolution.
Bearing resolution
Bearing resolution is the ability of the radar to display as separate pips the
echoes received from two targets that are at the same range and close together.
It is proportional to the antenna length and reciprocally proportional to the
wavelength. The length of the antenna radiator should be selected for a bearing
resolution better than 2.5° (IMO Resolution). This condition is normally satisfied
with a radiator of 1.2 m (4 ft) or longer in the X-band. The S-band radar requires
a radiator of about 12 feet (3.6 m) or longer.
Range resolution
Range resolution is the ability to display as separate pips the echoes received
from two targets that are on the same bearing and close to each other. This is
determined by pulselength only. Practically, a 0.08 microsecond pulse offers the
discrimination better than 40 m as do so with all FURUNO radars.
Test targets for determining the range and bearing resolution are radar reflectors
having an echoing area of 10 m2.
Bearing accuracy
One of the most important features of the radar is how accurately the bearing of
a target can be measured. The accuracy of bearing measurement basically
depends on the narrowness of the radar beam. However, the bearing is usually
taken relative to the ship’s heading, and thus, proper adjustment of the heading
line at installation is an important factor in ensuring bearing accuracy. To
minimize error when measuring the bearing of a target, put the target echo at the
extreme position on the screen by selecting a suitable range.
Range measurement
Measurement of the range to a target is also a very important function of the
radar. Generally, there are two means of measuring range: the fixed range rings
and the variable range marker (VRM). The fixed range rings appear on the
screen with a predetermined interval and provide a rough estimate of the range
to a target. The variable range marker’s diameter is increased or decreased so
that the marker touches the inner edge of the target, allowing the operator to
obtain more accurate range measurements.
2-2
2. RADAR OBSERVATION
2.2
False Echoes
Occasionally echo signals appear on the screen at positions where there is no
target or disappear even if there are targets. They are, however, recognized if
you understand the reason why they are displayed. Typical false echoes are
shown below.
Multiple echoes
Multiple echoes occur when a transmitted pulse returns from a solid object like a
large ship, bridge, or breakwater. A second, a third or more echoes may be
observed on the display at double, triple or other multiples of the actual range of
the target as shown below. Multiple reflection echoes can be reduced and often
removed by decreasing the gain (sensitivity) or properly adjusting the A/C SEA
control.
True

Own ship
Multiple

Multiple echoes
Sidelobe echoes
Every time the radar pulse is transmitted, some radiation escapes on each side
of the beam, called "sidelobes." If a target exists where it can be detected by the
side lobes as well as the main lobe, the side echoes may be represented on
both sides of the true echo at the same range. Side lobes show usually only on
short ranges and from strong targets. They can be reduced through careful
reduction of the gain or proper adjustment of the A/C SEA control.

A relatively large target close to your ship may be represented at two positions
on the screen. One of them is the true echo directly reflected by the target and
the other is a false echo which is caused by the mirror effect of a large object on
or close to your ship as shown in the figure below. If your ship comes close to a
large metal bridge, for example, such a false echo may temporarily be seen on
the screen.

SART (Search and Rescue Transponder)
2.3.1
SART description
A Search and Rescue Transponder (SART) may be triggered by any X-Band (3
cm) radar within a range of approximately 8 nm. Each radar pulse received
causes it to transmit a response which is swept repetitively across the complete
radar frequency band. When interrogated, it first sweeps rapidly (0.4 µs) through
the band before beginning a relatively slow sweep (7.5 µs) through the band
back to the starting frequency. This process is repeated for a total of twelve
complete cycles. At some point in each sweep, the SART frequency will match
that of the interrogating radar and be within the pass band of the radar receiver.
If the SART is within range, the frequency match during each of the 12 slow
sweeps will produce a response on the radar display, thus a line of 12 dots
equally spaced by about 0.64 nautical miles will be shown.
When the radar to the SART is reduced to about 1 nm, the radar display my
show also the 12 responses generated during the fast sweeps. These additional
dot responses, which also are equally spaced by 0.64 nautical miles, will be
interspersed with the original line of 12 dots. They will appear slightly weaker
and smaller than the original dots.

Showing SART marks on the radar display
This radar is equipped with a feature that optimally sets up the radar for SART
detection. This feature automatically detunes the radar receiver out of its best
tuning condition. This erases or weakens all normal radar echoes, but the SART
marks are not erased because the SART response signal scans over all
frequencies in the 9 GHz band. When the radar approaches the SART in
operation, the SART marks will enlarge to large arcs, blurring a large part of the
screen.

2.3.3
General remarks on receiving SARTs
SART range errors
When responses from only the 12 low frequency sweeps are visible (when the
SART is at a range greater than about 1 nm), the position at which the first dot is
displayed may be as much as 0.64 nm beyond the true position of the SART.
When the range closes so that the fast sweep responses are seen also, the first
of these will be no more than 150 meters beyond the true position.
Radar bandwidth
This is normally matched to the radar pulselength and is usually switched with
the range scale and the associated pulselength. Narrow bandwidths of 3-5 MHz
are used with long pulses on long range scales and wide bandwidths of 10-25
MHz with short pulses on short ranges.
A radar bandwidth of less than 5 MHz will attenuate the SART signal slightly, so
it is preferable to use a medium bandwidth to ensure optimum detection of the
SART.
Radar side lobes
As the SART is approached, side lobes from the radar antenna may show the
SART responses as a series of arcs or concentric rings. These can be removed
by the use of the anti-clutter sea control although it may be operationally useful
to observe the side lobes as they may be easier to detect in clutter conditions
and also they will confirm that the SART is near to own ship.

RACON
A RACON is a radar beacon that emits radar receivable signals in the radar
frequency spectrum (X- or S-band). There are several signal formats; in general,
the RACON signal appears on the radar screen as a rectangular echo
originating at a point just beyond the position of the radar beacon. It has a Morse
coded pattern. Note that the position on the radar display is not accurate.

Radar Target Enhancer (RTE)
An RTE is a radar transponder is mounted on navigation buoys and masts of
small crafts to significantly improve their detection by radar. Unlike a SART or
RACON, which are passive, the RTE receives a radar signal, amplifies it and
re-transmits it, with the intention of making the target's signal look larger on a
radar display. The RTE is available in X-band and S-band types.

TARGET TRACKING (TT)
3.1
Usage Precautions
WARNING
No one navigational aid should be relied
upon for the safety of vessel and crew.
The navigator has the responsibility to
check all aids available to confirm
position. Electronic aids are not
a substitute for basic navigational
principles and common sense.
• This TT automatically tracks
automatically or manually acquired radar
targets and calculates their courses and
speeds, indicating them by vectors. Since
the data generated by the auto plotter
are based on what radar targets are
selected, the radar must always be
optimally tuned for use with the auto
plotter, to ensure required targets will not
be lost or unwanted targets such as sea
returns and noise will not be acquired
and tracked.
• A target does not always mean a landmass, reef, ships or other surface vessels
but can imply returns from sea surface
and clutter. As the level of clutter changes
with environment, the operator should
properly adjust the A/C SEA, A/C RAIN
and GAIN controls to be sure target
echoes are not eliminated from the
radar screen.
CAUTION
The plotting accuracy and response of
this TT meets IMO standards.
Tracking accuracy is affected by the
following:
• Tracking accuracy is affected by course
change. One to two minutes is required to
restore vectors to full accuracy after an
abrupt course change. (The actual
amount depends on gyrocompass
specifications.)
• The amount of tracking delay is inversely
proportional to the relative speed of the
target. Delay is on the order of 15—30
seconds for high relative speed; 30—60
seconds for low relative speed.
• Display accuracy is affected by the
following:
- Echo intensity
- Radar transmission pulsewidth
- Radar bearing error
- Gyrocompass error
- Course change (own ship and target)
The data generated by TT, AIS and
video plotter are intended for
reference only.
Refer to official nautical charts for
detailed and up-to-date information.

Entering Own Ship's Speed
The TT requires own ship's speed and heading data. The speed can be STW,
SOG or echo-referenced speed (based on 3 max. stationary objects). Manual
input is also possible.
For automatic or manual input, see section 1.13. For echo-referenced speed
input follow the procedure below.
3.4.1
Echo-referenced speed input
The use of echo-referenced speed is recommended when:
• The speed log is not operating properly or not connected to the radar.
• The vessel has no device (doppler sonar, speed log, etc.) that can measure
ship's bow-stern, port-starboard movement.
If you select echo-referenced speed, the TT calculates own ship's speed relative
to a fixed reference target. The number of targets may be R1, R2 or R3. When a
plural of objects are selected, the mean value is used, for stabilization and
speed.
1. With the cursor inside the effective display area, roll the scrollwheel to
display "REF MARK / EXIT" in the guidance box.
2. Select a small fixed island or any radar prominent point located at 0.2 to 24
nm from own ship.

3. TARGET TRACKING (TT)
3. Push the left button to enter the reference mark.
The reference target mark (see below) appears at the cursor position and
the own ship position data label changes from "LOG," "NAV" or "MANUAL" to
"REF." Note that it takes three minutes before a new speed is displayed. If
tracking has failed for a reference target, the target is marked with a lost
target mark (symbol formed with two triangles).

4. Repeat steps 2-3 to continue entering reference marks. Three may be
entered.
Notes on speed input by reference target
• Reference targets are only used for the calculation of true speed.
• Do not use reference target generated true speed to calculate relative speed.
Relative speed data is not accurate because response to speed change is
slow, hampering the TT's ability to accurately judge the possibility of collision.
• Select a stationary target as a reference target to calculate own ship speed as
ground tracking speed. Do not choose a moving target as a reference target. A
moving target produces error in the vector for TT and AIS, which results in
wrong collision avoidance information. Further, an unstable stationary target
produces inaccurate speed data and the target itself may become lost.
• When a reference target is lost or goes out of the acquisition range, that
reference target mark blinks and the indication "REF TARGET LOST" appears
in the alarm box. If all reference targets are lost, the speed indication reads
"*.*" Select a different reference target if currently selected one is lost.
• When all targets are deleted, the reference target mark is also deleted and the
target-based speed becomes invalid. The speed is indicated as BTREF where
BT means Bottom Track (speed over ground).
• Reference targets may be marked with a vector. This can be done with 3 REF
TARGET VECTOR on the TT TARGET menu.
• Loss of reference target will affect the calculation of true speed and true
course of targets. Further, own ship speed will be inaccurate.

Symbol
Meaning
Immediately after acquisition, this plotting symbol is shown in
broken lines.
Within one minute after acquisition, a vector appears to show a
trend of movement.
Within three minutes after acquisition, the plotting symbol changes
to a small circle, indicating steady-state tracking condition.
Note 1: For successful acquisition, the target to be acquired should be within 0.1
to 24 nm (or 32 nm, depending on initial setting) from own ship and not
obscured by sea or rain clutter.
Note 2: When the capacity for manual acquisition is reached, the message
"TARGET FULL(MAN)" is displayed at the screen bottom. Cancel
tracking of non-threatening targets if you wish to acquire additional
targets manually.
Note 3: Target number is normally not shown. On the A, B, C and W type radars
it appears when the cursor is placed on a TT symbol.
CAUTION
Target Swap
When a target being tracked nears another
target being tracked, the targets may be
"swapped". When two targets acquired
either automatically or manually come close
to each other, one of the two may become
a Lost Target. Should this happen, manual
re-acquisition of the Lost Target may be
required after the two have separated.

target with suffix "T" (True) or "R" (relative). CSE/STW are shown for manual
speed and speed through the water.
CPA/TCPA: CPA (Closest Point of Approach) is the closest range a target will
approach to own ship. TCPA is the time to CPA. Both CPA and TCPA are
automatically calculated. When the CPA has passed clear of own ship, it is
indicated by a TCPA with a negative (-) sign. TCPA is counted to 99.9 min and
beyond this, it is indicate as TCPA> -99.9MIN.
BCR/BCT: BCR is the closest range at which the selected target is predicted to
cross your ship’s bow. BCT is the time at which the selected target is predicted
to cross your ship’s bow.

Description of vectors
Ground stabilization and sea stabilization
Target vectors can be ground stabilized or sea stabilized. You can select ground
or sea stabilization from the SPEED menu. Select BT(Bottom Tracking) for
ground stabilization or WT(Water Tracking) for sea stabilization. The TT
VECTOR box shows the stabilization mode as TRUE-G or TRUE-S.
Sea stabilization is a mode where own ship and all targets are referenced to the
sea using a compass heading and single-axis log water speed inputs. Ground
stabilization is a mode where own ship and all targets are referenced to the
ground using the ground track or set and drift inputs. If the accuracy seems
unsatisfactory, enter set and drift corrections. Note that set and drift cannot be
used on the IMO radar when the radar is displaying AIS targets.

Past Position Display
The past position display shows equally time-spaced dots marking the past
positions of any targets being tracked.
A new dot is added every minute (or at other preset time intervals) until the
preset number is reached. If a target changes its speed, the spacing will be
uneven. If it changes the course, its plotted course will not be a straight line.

Set and Drift
Set, the direction in which a water current flows, can be manually entered in
0.1-degree steps. Drift, in another word Rate, the speed of tide, can also be
entered manually in 0.1 knot steps.
When course through water and speed through water are available, activate set
and drift to get course over ground and speed over ground.
Set and drift corrections are beneficial for increasing the accuracy of vectors and
target data. Refer to the tide table on board the ship for setting information.
These values are applied to all targets. If stationary targets have vectors, set and
drift values should be adjusted until they lose vectors.

acts as an automatic acquisition area when automatic target acquisition is active.
Any targets entering the zone will be automatically acquired.
When a target enters an acquisition zone, the buzzer sounds and the indication
TT NEW TARGET (or AIS NEW TARGET) appears (in red) in the Alert Box. The
symbol of the offending target is red and flashing. Further, the AIS display is
automatically turned on if it is off.
3.14.1
Activating an acquisition zone
One or two acquisition zones may be activated. The No. 1 acquisition zone is
available between 3 and 6 nm and the No. 2 acquisition zone can be set
anywhere when the No. 1 zone is already in use. The TT/AIS acquisition zone’s
lines are white and dashed so as to distinguish them from the radar target alarm.
The procedure below shows how to set an acquisition zone, using the example
at the bottom of the page.
1. Use the trackball to select one of the AZ (Acquisition Zone) boxes at the right
side of the screen.

When a TT or AIS target enters the zone, the indication TT NEW TARGET or AIS
NEW TARGET appears (in red) in the Alert Box and the offending target flashes.
For the AIS, all sleeping targets are changed to activated targets.
Note 1: If you wish to create an acquisition zone having a 360-degree coverage
around own ship, set point B in almost the same direction (approx. ±3°)
as point A then push the left button.
Note 2: If the range scale is changed to less than half of the acquisition zone,
"Azx (x=1 or 2) OUT" is shown in light-blue in the AZ box.If the left
button is pushed in this state, the acquisition zone goes into "sleep"
state and the guidance box reads "AZ WORK L = DELETE."
Note 3: The default acquisition zone is fan shaped. It may also be a polygon
having 3-10 points. For details, see section 3.14.5.
Note 4: If both acquisition zones are displayed, maximum of four polygon points
are shown.
Note 5: TT and AIS are automatically set to TT=AUTO and AIS=DISP,
respectively, when an AZ is activated in the following conditions:
TT:
TT=OFF or TT=MANUAL 100

Trial Maneuver
The trial maneuver feature simulates the effect on all tracked targets against
own ship's maneuver. Enter your expected course, speed and time-to-maneuver
to find the relationship between your ship and other ships against your planned
maneuver. Further, set CPA and TCPA values to find possible collision situations.
Enter various courses and speeds until a dangerous situation is resolved. The
trial manuever feature proceeds without interrupting the updating of target
information.
For more accurate results, use relative motion and sea stabilization (ground
tracking) and be sure that own ship's characteristics such as acceleration and
turning performance have been properly set in the initial settings during the
installation. Take into consideration own ship's maneuvering characteristics such
as rudder delay, turning delay and acceleration delay. This is particularly
important on large vessels.
3.16.1
Types of trial maneuvers
There are two types of trial maneuvers: static and dynamic.
Dynamic trial maneuver
A dynamic trial maneuver displays
predicted positions of the tracked targets
and own ship. You enter own ship's
intended speed and course with a certain
"delay time." Assuming that all tracked
targets maintain their present speeds
and courses, the targets' and own ship's
future movements are simulated in
one-second increments indicating their
predicted positions in 30-second
intervals as illustrated below.
Delay time = 2 m 30 s.
Present own
ship position
The delay time represents the time lag
from the present time to the time when own ship will actually start to change her
speed and/or course. How much the delay is set the situation starts immediately
and is updated every 0.5 seconds.
In the example shown below, own ship will advance straight ahead (even after a
maneuver) for a delay time of 2:30 then alters speed and course until
operator-specified intended speed and course are achieved (position OS5 in this
example). OS6 and OS7 show changes in course and speed and OS8 show that
the ship has completed course and speed adjustments.
3-26
3. TARGET TRACKING (TT)
Static trial maneuver
The static trial maneuver shows the relationship between your ship and tracked
targets at the completetion of the trial maneuver. Enter expected course and
speed and delay time until start of a maneuver and the expected position of your
ship and tracked targets at the end of the trial maneuver are shown on the
display.
By shortening and extending the trial time you can find the safe time to make a
maneuver. Thus, the static trial maneuver will be convenient when you wish to
know the maneuver result immediately.

shows "TRAIL 00:00" (00:00 is trial maneuver time).
The time indication depends on trial mode:
Dynamic mode: The position of your ship and tracked targets is updated and
displayed every 30 seconds.
Static mode: The position of your ship and tracked targets when set course and
speed are reached are displayed. The progress time until the position is reached
is indicated on the display. The trial time can be changed from the Trial Time box.
Put the cursor in the Trial Time box and roll the scrollwheel. The position of
targets at the end of selected time is shown. Increase or decrease the time to
get a safe manuever. When the cursor is removed from the box the original
positions of your ship and tracked targets are restored. If a manuever is unsafe,
change speed, course and delay until it is safe.
The trial maneuver takes place with the letter "T" displayed at the bottom of the
screen. The time appears at the top right side of the display. If any tracked target
is predicted to be on a collision course with own ship (that is, the target ship
comes within preset CPA/TCPA limits), the target plotting symbol is red. If this
happens, change own ship's trial speed, course or delay time to obtain a safe
maneuver.
3.16.3
Terminating a trial maneuver
A trial maneuver is automatically terminated at the end of the fixed time and the
normal radar display is restored. The time of termination depends on the trial
mode as follows:
Dynamic mode: The trial is terminated when 60 minutes is shown in the Trial
Time Box.
Static mode: The trial is terminated when there is no key operation within one
minute.
To terminate the trial maneuver manually, put the cursor in the Trial Time box
then push the left button to show TRAIL OFF in the box.

Criteria for Selecting Targets for Tracking
The FURUNO TT video processor detects targets in midst of noise and
discriminates radar echoes on the basis of their size. Target whose echo
measurements are greater than those of the largest ship in range or tangential
extent are usually land and are displayed only as normal radar video. All smaller
ship-sized echoes that are less than this dimension, are further analyzed and
regarded as ships and displayed as small circles superimposed over the video
echo.
When a target is first displayed, it is shown as having zero true speed but
develops a course vector as more information is collected. In accordance with
the International Marine Organization Automatic Radar Plotting Aid (IMO TT)
requirements, an indication of the motion trend should be available within 20
scans of antenna and full vector accuracy within 60 scans. The FURUNO TTs
comply with these requirements.
Acquisition and tracking
A target which is hit by five consecutive radar pulses, is detected as a radar echo.
Manual acquisition is done by designating a detected echo with the trackball.
Automatic acquisition is done in the acquisition areas when a target is detected
5-7 times continuously depending upon the congestion. Tracking is achieved
when the target is clearly distinguishable on the display for 5 out of 10
consecutive scans, whether acquired automatically or manually. Required
tracking facilities are available within 0.1-32 nm on range scales including 3, 6,
12 nm, full plotting information is available within one scan when the range scale
has been changed.
Targets not detected in five consecutive scans become "lost targets."
Quantization
The entire picture is converted to a digital from called "Quantized Video." A
sweep range is divided into small segments and each range element is "1" if
there is radar echo return above a threshold level, or "0" if there is no return.
The digital radar signal is then analyzed by a ship-sized echo discriminator. As
the antenna scans, if there are five consecutive radar pulses with 1’s indicating
an echo presence at the exact same range, a target "start" is initiated. Since
receiver noise is random, it is not three-bang correlated, and it is filtered out and
not classified as an echo.
The same is true of radar interference. Electronic circuits track both the closet
and most distant edges of the echo. At the end of the scanning of the echo, the
discriminator indicates the measured maximum range extent and total angular
extent subtended by the echo. If the echo is larger than a ship-sized echo in
range extent and/or angular width, adjusted as a function of range, it is declared
to be a coastline and the closet edge is put into memory as a map of the area.
3-32
3. TARGET TRACKING (TT)
This land outline is used to inhibit further acquisition and tracking of ship-sized
echoes beyond the closest coast outline. Five consecutive scans of coastal
outline are retained in memory to allow for signal variation. All smaller echoes
are declared to be ship sized and the middle of the leading edge is used to
provide precise range and bearing coordinates of each echo on every scan. This
range/bearing data is matched to previous data and analyzed from scan-to-scan
for consistency. When it is determined to be as consistent as a real target,
automatic acquisition occurs and tracking is initiated. Continued tracking and
subsequent calculation develop the relative course and speed of the target.
The true course and speed of own ship are computed from own ship's gyro and
speed inputs, and the resulting course and speed of each tracked target is easily
computed by vector summing of the relative motion with own ship’s course and
speed. The resulting true or relative vector is displayed for each of the tracked
targets. This process is updated continually for each target on every scan of the
radar.
Qualitative description of tracking error
The FURUNO TT's accuracy complies with or exceed IMO standards.
Own ship maneuvers
For slow turns there is no effect. For very high turning rates (greater than
150°/minute, depending on gyro), there is some influence on all tracked targets
that lasts for a minute or two then all tracked targets revert to full accuracy.
Other ship maneuvers
Target ship courses, lag 15 to 30 seconds at high relative speed, or 3 to 6
seconds at low (near 0) relative speed. It is less accurate during a turn due to lag,
but accuracy recovers quickly.
3-33
3. TARGET TRACKING (TT)
3.19
Factors Affecting TT Functions
Sea returns
If the radar anti-clutter control is adjusted properly, there is no serious effect
because distant wave clutter, not eliminated by this control, is filtered out by
more than one bang correlation and scan-to-scan matching of data.
Rain and snow
Clutter can be acquired and tracked as targets. Adjust the A/C RAIN control. If it
is heavy rain, switch to S-band if provided, or switch on the interference rejector
on the radar. If heavy clutter still exists, switch to manual acquisition. Accuracy
can be affected.
Low clouds
Usually no affect. If necessary, adjust the A/C RAIN control.
Non-synchronous emissions
No effect.
Low gain
Insufficient or low radar receiver gain will result in some targets not being
acquired at long distance. TT display will be missing on one or more targets that
could only be visible if the radar sensitivity control (GAIN control) were
increased.
The setting of the correct radar receiver gain is not critical but the target should
be on the radar PPI and be clearly visible and well defined.
Manual acquisition is done if a target is positively displayed more than once.
Automatic acquisition is done when the target is detected 5-7 times continuously.
Tracking is achieved when the target is detected five times (not necessarily
continuously) out of 10 scans. If not detected six times out of 10 scans, the
target will become a "lost target." The TT will acquire a radar echo that is present
once in every six antenna scans and continue tracking if 1 in 10.
Second trace echoes
When the radar beam is super refracted, strong echoes may be received at such
long ranges that they appear on a different timebase sweep than the transmitted
pulse. This gives an incorrect range indication. Second and third trace echoes
can be tracked if they are consistent enough to meet acquisition and tracking
criteria but target course and speed data will be in error.
3-34
3. TARGET TRACKING (TT)
Blind and shadow sectors
Radar shadow or blind areas caused by obstructions aboard ship, for example,
funnels and masts, in the path of the radar beam can result in reduction of radar
beam intensity in that particular direction. This may eliminate the detection of
some targets. The TT system will lose track of targets shortly after they are lost
on the radar picture and if they remain in a blind zone. These targets will
however be acquired and tracked when they pass out of the blind zone and
again present normal radar echo. The angular width and bearing of any shadow
sector should be determined for their influence on the radar. In certain cases
false echoes in the shadow sector cause the TT system to acquire, track, and
vector them. Shadow sectors should be avoided.
Indirect echoes
A target at close range is usually picked up directly, but it can also be received
as reflection from a large, flat surface. This will result in the radar presenting two
or more echoes on the display, each at a different range. The TT can acquire
and track the false echo if it is detected by five consecutive scans. Reduction in
radar gain can eliminate the multiple echoing but care should be taken as range
detection also will be reduced.
Radar interference
If interference is extreme due to another radar operating at close range, spiral
"dotting" and/or false targets may appear momentarily. The interference rejector
can clear the display.
To receive radar beacon or SART signals, turn on "SART" in the ECHO menu.

AIS OPERATION
The FURUNO AIS (Automatic Identification System) model FA-100 or FA-150
exchanges with other AIS-fitted ships all data and information required by the
SOLAS 1994 as amended. However, they are displayed in text form. By
interfacing the FA-100 or FA-150 with this radar, the AIS information is
graphically indicated together with the radar and TT information.
For the IMO specification, position data must be fixed by WGS-84 geodetic
datum and speed input must be ground tracking. If other type of datum is input,
the error message "DATUM" appears and the AIS feature is inoperative. This
restriction does not apply to other types.
When AIS is active, MANUAL and REF in the speed source selection window
are shown in gray to indicate they are not available for selection.
You may disable or enable the AIS display from the AIS DISP box.

Lost Target
A target is declared a lost target when it fails to produce data for six minutes or
five reporting intervals, whichever is the shorter. When this occurs, the target is
marked with the (flashing) lost target symbol and the indication "LOST" appears
in the Alert Box. To acknowledge a lost target, press the [ALARM ACK] key, or
use the trackball to select the ALARM ACK box then push the left button.
Lost target
Note 1: If a TT lost target mark is displayed when the [ALARM ACK] key is
pressed (or the ALARM ACK box is clicked) to acknowledge an AIS lost
target, the TT lost target also is erased.
Note 2: The AIS data transmission interval depends on target’s speed. For
example, the data is transmitted every 10 seconds on ship speed of 0 to
14 knots and every two seconds on the ship speed of more than 23
knots. For details see the owner’s manual of the AIS.

AIS Collision Alarm (CPA, TCPA)
The AIS continuously monitors the predicted range at the Closest Point of
Approach (CPA) and predicted time to CPA (TCPA) of each AIS target. When the
predicted CPA of an AIS target becomes smaller than a preset CPA range and its
predicted TCPA less than a preset TCPA limit, the audio alarm sounds and AIS
COLLISION appears (in red) in the Alert Box. In addition, the symbol of the
offending AIS target is red and flashes together with its vector.
CPA/TCPA alarm ranges must be set up properly taking into consideration the
size, tonnage, speed, turning performance and other characteristics of own ship.
The reference point for CPA, TCPA calculation may be selected from antenna
position or conning position. For further details, see section 1.50.

VIDEO PLOTTER OPERATION
5.1
General
The video plotter does the following functions:
• Plots own and other ships’ tracks. (Plotting of other ships’ tracks not available
on IMO type.)
• Enters waypoints, nav lines and marks.
• Creates and displays radar maps.
• Records data onto memory cards (optional card interface required).
• It uses two types of memory cards, a memory card (RAM card) for storing own
ship and other ship’s tracks and marks, and a digital chart card (ROM card).
• 30 nav lines may be stored and each line may contain up to 30 waypoints.
One nav line may be shown on the display. 200 waypoints are available. Own
ship and other ship tracks may be stored at a selected interval.
• Charts (A, B, C and W types) are superimposed on the radar picture without
disturbing the radar observation. The chart area is dependent on the radar
range in use.
5.2
Display Modes
This radar has display modes as follows.
• IMO, A type:
Radar, Radar + Plotter, Anchor Watch
• B, C, W type: Radar, Radar + Plotter, Plotter
Use the DISPLAY MODE box to select a mode. (When the video plotter mode is
displayed more than five seconds, the radar automatically goes into standby.)

Radar Map
A radar map is a combination of map lines and symbols whereby the user can
define and input the navigation data, route planning and monitoring data. The
radar map may contain 20,000 points of data. The map data can be saved to
facilitate repeated use on a routine navigation area. The user can create a radar
map on-real time while using the radar for navigation or at leisure time at anchor
or while the radar is not being used. Place of a map can be made for any
waterways apart from the actual own ship location.
The radar map does not affect any radar function.

MAINTENANCE,
TROUBLESHOOTING
Periodic checks and maintenance are important for proper operation of any
electronic system. This chapter contains maintenance and troubleshooting
instructions to be followed to obtain optimum performance and the longest
possible life of the equipment. Before attempting any maintenance or
troubleshooting procedure please review the safety information below.
WARNING
Do not open the equipment.
Hazardous voltage which can
cause electrical shock exists
inside the equipment. Only
qualified personnel should
work inside the equipment.
Turn off the radar power
switch before servicing the
antenna unit. Post a warning sign near the switch
indicating it should not be
turned on while the antenna
unit is being serviced.
Prevent the potential risk of
being struck by the rotating
antenna.
A transmitting radar
antenna emits electromagnetic waves, which can be
harmful, particularly the
eyes.
Wear a safety belt and hard
hat when working on the
antenna unit.
Serious injury or death can
result if someone falls from
the radar antenna mast.
NOTICE
Do not apply paint, anti-corrosive sealant
or contact spray to coating or plastic
parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.

4. Longitude Error Table (on 96 nm range scale)
The longitude lines concentrate on the north pole and south pole, namely, 1 nm is
equivalent to 1 minute at 0 degree latitude, 2 minutes at 60 degrees latitude, 3 minutes at
70 degrees latitude and so on. For this reason, a longitude error occurs on the radar display.
For example, when own ship is at 60°N and 135°E, even if the cursor indication is 62°N and
139°E, the real cursor position is deviated to the left (west) side. The table below shows the
longitude error, represented from 0° to 90° at 96 nm from the radar center (own ship).
