Target Analyzer (Non-IMO only)

The target analyzer function analyzes echoes and assists the operator to determine dangerous targets. This function is particularly useful under heavy rain/snow or where there is surface reflection, which can cause interference and noise.

The target analyzer function can also place hatching over heavy rain areas, reducing the visible interference and allowing a clearer view of potential targets.

Echoes are displayed in five different colors to assist the operator in identifying targets. The colors and their respective echoes change depending on the echo color se-

lected from the [BRILL] menu (see section 1.43.2) are shown in the table below.

The following example figures show the manner in which this function affects displayed echoes.

No echo adjustment

(Target analyzer off, EAV off, hatching off)

Rain, moving targets and surface reflections are all displayed with no filtering.

Minimal echo adjustment

(Target analyzer on, EAV off, hatching off)

Echoes are colored, surface reflections are filtered, rain is displayed.

1-47


Moderate echo adjustment

(Target analyzer on, EAV on, hatching off)

Echoes are colored, surface reflections and rain are filtered.

Maximum echo adjustment

(Target analyzer on, EAV on, hatching on)

Echoes are colored, surface reflections are filtered, rain is displayed in gray colored hatching.

Note 1: This function works best when the settings for [GAIN], [STC], [RAIN], [NOISE

REJECT] and [VIDEO CONTRAST] are properly adjusted (surface reflections are displayed in green and rain is displayed in gray).

Note 2: This function recognizes moving targets as approaching targets. Buoys and other stationary objects are not recognized as approaching targets by this function.

Note 3: The target analyzer function requires a short period of time to analyze echoes and display them on-screen. If your antenna revolves at more than 40 rpm, moving targets may not be displayed correctly. For this reason, caution is advised when using the target analyzer function.

What is “hatching”?

Where echo averaging may hide light rain on the display, the hatching feature, when activated, places a gray “veil” over the areas where rain is detected. This allows the operator to see where the rain is without affecting the quality of the displayed echoes.

1.37.1

How to activate/deactivate the target analyzer

1. Select the [CUSTOMIZE ECHO] box, then press the right button.

2. Select [TARGET ANALYZER], then push the ADJUST knob.

1.38

Target Alarm

The target alarm serves to alert the navigator to targets (ships, landmasses, etc.) entering a specific area, with audiovisual alerts.

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 (target alarm zone 1) and any distance (target alarm 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.

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.

Note: The [ALR1] and [ALR2] boxes are not displayed when the setting for [AZ/ALR

SELECT] in the [TT•AIS] menu is set to the default setting [AQUISITION ZONE]. To enable this function, set [AZ/ALR SELECT] in the [TT•AIS] menu to [TARGET ALARM

ZONE].

• An antenna unit cannot be controlled from multiple display units. Select one Master display unit for one antenna unit. If two antenna units are set as masters, the display last-set as master becomes the master and all other displays are automatically changed to slave.

• An antenna unit without a Master display cannot be selected on the sub display units. If there is no antenna unit set as master, the lowest number display is automatically set as master.

• If the Alert 740 "XT RADAR ERROR" appears, do one of the following as applicable:

- If only your antenna is not displayed on the [ANT SELECT] display, the LAN line in the Processor Unit may be faulty. In this case, use the standalone mode.

- If the antenna that was in use does not appear on the [ANT SELECT] display, the

LAN line in other Processor Unit may be faulty. In this case, see the preceding page for how to select a different antenna unit

• When the Network fails, the Interswitch does not work, but standalone operation is possible.

• Radar functions are controlled independently, dependently or commonly depending on selection as Master or Slave (see the table below).

How to check the radar’s performance

The range scale is automatically set to 24 NM. The radar screen will show arcs. If the radar transmitter and receiver are in good working conditions in as much as the original state when the monitor was turned on, the innermost arcs should appear between

8.0 NM to 19.8 NM. The performance monitor can observe a total of 10 dB loss in transmitter and receiver.

How to set the number of arcs

1) Open the [MAIN MENU].

2) Select [ECHO], then push the ADJUST knob.

3) Select [PM ARC], then push the ADJUST knob.

4) Select [2], [3], [5] or [6] as appropriate, then push the ADJUST knob.

5) Close the menu.

The figure belows shows an example where [PM ARC] is set to [5].

Contact your dealer for advice.

(For magnetron radars, have a technician check the magnetron.

Note 1: The lengths of the arcs can vary according to installation environment. Judge the strength of the echo that appears within 60° from the arc location to confirm if the radar is working properly or not.

Note 2: The location of the arcs changes according to the [PM ARC] setting.

Turn the performance monitor off when finished.

How to Change the Reference Position

The reference position for measurements (range, bearing, etc.) and markers (heading line, stern mark, etc.) can be the radar antenna position ([ANT]) or the consistent common reference point ([CCRP]).

The reference position 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.

[CCRP] for this series of radars is fixed at the conning position and [ANT] is fixed at the radar antenna position.

To change the reference position, use the Touchpad to place the cursor over the "REF

POINT" indication at the top of the screen, then press the left button to select [ANT] or [CCRP] as applicable. You can also change the reference by rotating the ADJUST knob when the cursor is placed over the indication.

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.
