For relative motion (RM) and true motion (TM)
Relative motion indicates the motion of surrounding targets with own ship’s position fixed at the center
of the screen.
Because own ship position is centralized, fixed targets such as the land also move on the display while
the ship is moving.
True motion indicates the motion of the target as a center of the specified bearing.
Fixed targets that do not move in any direction stay on the display as they were and actually moving
targets move on the screen.
*No true motion [TM] is available for [H UP] mode because the heading always continues to move.
Relative motion (RM): The own ship position is fixed and the other surrounding targets move on the
screen.
This is useful for monitoring the surrounding situation from the own ship’s
position as a center.

・This item is to set vector display mode: Relative or True.
・ True motion displays course and speed of the target actually moving, while relative motion displays
relative course and speed of the target sawn from the own ship’s position.
In true vector mode, vector orientation is true course of target and length is proportional to its speed.
Own ship vector is also displayed in true vector mode.
Relative vector display does not show real motion of the target but show relative motion to the own
ship.
Target with its vector orientated to own ship is dangerous ship.
Accordingly, true vector is used for grasping actual situation of target while relative vector to grasp
CPA of target.

“Position” calculates movement distance from course and latitude/longitude.
“Position” selection is effective to obtain stable trail under rough current where error of speed sensor is
large,
(9) Rel mode (Relative bearing criteria)
This is to select the signal (ship’s bearing or true) as criteria to record trails, in case trail mode is used
as “REL”.
Ship’ bearing: Trails are recorded taking the ship’s bearing as criteria.
The echo moving by own ship’s turn remains as trail.
True
: This is active when such a bearing sensor as gyro, GPS compass is connected,
to record trails based on the true bearing from the bearing sensor.
The echo moving by own ship’s turn is not recorded as trail. When compared with
the ship’s bearing criteria, trail image is clearer and it is easier to see the relative position
with the other vessel.
(10) Trail detection level (1 to 6)
Designate trail display image strength selecting from value 1 to 6.
1 display trail even from weak image signal.
6 display trail only from strong image signal.
IMPORTANT: Lower detection level may display trail only in the position where target is not shown on
the screen.
(11) Interference rejection (IR)
Other ship’s radar of the same frequency band may cause interference noise on the screen. This
interference effect is not uniform but in most cases spiral or radius shape. This device provides
interference removal function to reduce these effects.
• Designate value is [Off, 1, 2, 3, 4, 5] and large value is for stronger removal effect.
• Too strong interference removal may mask small target.
(12) Display target stable using signal processing.
There are two types of method for screen correlation process: One is residual image process and
another is averaging.
The setup values 1 and 2 represent residual image process and the set up value 3 represents
averaging process.
• Residual image process:
The image that has appeared only once is not immediately deleted, but displayed with the residual
image.
At the setup value 1, the image that has appeared only once is displayed after weakened in 3 steps.

Display of residual image when an image was caught with Scan1 only
This is effective to confirm an image that appears only once per scan because the object may be
hidden between the waves.
• Averaging process:
At setup value of 3, images are averaged.
When there is a stable image such as a ship among sporadic images such as sea clutter, the sea
clutter is erased by averaging to leave the stable image.
Due to the averaging process, even though stable strong images appeared just after transmission,
they are displayed weakly and gradually turn into strong images.

(9) Video mode
This is a function to change the relation between the strength of signal of target echo and their display
gradation.
At [VIDEO 0], the difference of signals strength between dark images and bright images becomes
larger. As the numerical figure becomes larger as [VIDEO 1], [VIDEO 2] and [VIDEO 3], the difference
in signal strength becomes smaller.
At [VIDEO 4], the difference of signal strength becomes gradually smaller in the range at close to 5 NM
and becomes constant at 5 NM or higher. When the difference of signal strength is large, it will be easy
to display clutter at darker level and targets at brighter level.
When the difference of signal strength is small, images becomes sharper.
However, signal strength from small ships and buoys is weak, and the difference between clutter and
them is not large enough.
Therefore, it is necessary to display the clutter not to get in the way and not to overlook small ships and
course buoys.

Chapter 6 Principle of radar system
Chapter 6 Principle of radar system
6.1 What is radar system?
The radar is a navigation device that transmits a very high frequency radio wave referred to as
microwave from the antenna. The radar then receives the radio wave reflected by target(s) (e.g. other
ship, buoy, island, etc.) via the same antenna and converts the received radio wave to electronic
signals and sends these signals to the display unit. The radar makes it possible to find objects (targets),
such as other ships, rocks or coastline, not seen by eyesight at night or in fog and allows ships to avoid
these potential hazards.
As the antenna transmits while rotating, it is possible to see the current surrounding situation around
your vessel at a glace.
The microwave radiated from the radar is referred to as pulse wave and the transmitting and receiving
of these waves is alternated. Up to thousands of pulse waves are transmitted and received during one
360-degree rotation
The typical radar antenna is parabolic type or slotted array type and its performance is essential for
good radar performance. Some of factors affecting the quality of the target returns are antenna beam
width and side lobe level. The narrow beam width provides high resolution for angular orientation to
distinguish objects and the low side lobe level reduces false image effect.

7-1 What is Radar?
Side lobe
The main lobe means the strongest radiated beam sent from the specific antenna, and the other
weaker beams, are referred to as a side lobes. A side lobe level is a difference between the largest
side lobe level and main lobe level.

Beam width
Antenna beam width is defined as the angle where the radiation power density is within a half of
maximum power density (-3 dB) in main lobe (also, referred to as “half value width”).
6.2 Characteristics of radar radio wave
The radar radio wave propagates slightly along the ground (primarily line of sight). This characteristics
varies depend on density of atmosphere but is generally calculated according to the formula as shown
below, considering that the distance with radar sight D is about 6 % longer than the distance with
optical sight.

7-3 Characteristics of radar radio wave
Target hardness reflected
The strength of the reflected wave from a target varies depending on not only the distance from the
target, its height or size, but also its material and features. A target with a low degree of reflection or
low incident angle, such as FRP and wooden is not reflected well. Therefore, care shall be taken that
an FRP ship, a wooden vessel or an object such as sand, a sandbar and muddy cay are poor radar
targets.
Since the distance from the coastline, etc. to your ship on a radar image tends to be seen as longer
than that from the actual coastline, more caution should be used navigating around such objects..

Chapter 6 Principle of radar system
Radar shadow
Since radar radio wave is line of sight in nature your stack mast close to the antenna or, a large ship or
mountain can create blind spots for which the radar cannot penetrate.. In such cases, they may
completely or partially hide targets and cast a long shadow.
Since the shadow your stack or mast is known at the time of installation, proper selection of the
antenna location is necessary to reduce the shadow effect. Since targets less likely to be seen in this
shadow area than in open sea, extra attention should used in shadowed areas.
False image
An image that does not actually exist (false image) at sea may appear on the display.
The phenomena that causes false echoes are categorized and be described as follows:
● False image
The image of large physical object in a close proximity may appear in two different orientations. One is
a real image and the other is a false image caused by wave re-reflected on the stack or the mast, etc.
On the display, one image appears with a right distance and bearing, and another one appears in the
direction of a stack, a mast, etc. These images may also be generate by being re-reflected from
bridges and quays too.

● Duplicate target images
When there is a big reflective surface nearby and perpendicular at a close distance,( i.e. when your
ship is passed by a big ship, etc.), radio wave bounce between your ship and the other ship. Therefore,
2 to 4 images may appear at equal range in the direction of this target. The false image generated by
this multi-path reflection is referred to as “double targets”. In this case, the closest target is the real
one.
You will notice as the distance and bearing between own ship and the reflective target changes the
duplicate targets will disappear. Therefore, this false image can be easily distinguished.

Figure 67-6 False image caused by double image
The microwave beam radiated from the antenna has a side lobe in different direction than that of the
main beam. Since this side lobe level is lower than that of main beam, the effect is negligible for targets
at long range, but a close, strong reflecting target may cause false image appearing in a circular arc
shape.
CAUTION
Close to large targets such as land, a circular image may
appear.

Chapter 6 Principle of radar system
● False image of a distant target caused by “skip” phenomenon
Depending on a weather conditions, Skip appear caused by the temperature inversion layer of air, etc.
In this case, the unusual propagation of the radio wave may reach distant targets out of the radar
range. A target at more than the maximum range may appear as an image, and may be displayed as a
false image closer than an actual distance. This phenomenon is a result of the long range echo delay
time exceeds the transmission period, and is displayed as the echo in the following rotation. If the
range scale is changed and the target range changes, it can be judged as a false image.
6.3 Radar interference
When the radar with the same frequency band is used nearby, interference noise appears on a display.
Although appearance of interference is not constant, the shape is almost always swirling or radial.
This device features an interference rejection facility to reduce interference.
