5.5.4.5.5 Changing the content of settings (ADJUST)
The items in the ADJUST menu are used for setting up the equipment at installation, retrofitting, etc.
where various functional parameters need to be set up or reset. Once set up, resetting may be not necessary.
(1) Adjusting distance (TX TIME DELAY ADJ)
This adjustment is necessary to set up the distance to targets to within the specified accuracy. Before
proceeding to adjustment, set respective controls as follows:
(5) First, set the range scale to 0.25 NM, FTC to minimum, and GAIN to optimum level. Then adjust STC to
minimize the center spot ( a split of transmission energy shown like a sun) to a single dot.
(2) Adjusting the distance.
(2)-1 Select ADJUST by "common operations for CUSTOM". Use the up or down cursor key to select
TIMING ADJ from the pull-down menu and press the "ENT" key.
(2)-2 Find a straight linear target such as a jetty, bridge, etc.
(2)-3 Turn the rotary control either CW or CCW to obtain a linear echo shown like the one in Figure

(2) Adjusting angle (HEAD ADJ)
The purpose of this adjustment is to exactly orient the Heading Mark on the screen with the ship’s bow
direction.
Note: Heading offset value for open antenna is different from that of a radome antenna.
(1) In preparation for adjusting the angle, the following adjustments are to be conducted.
(1)-1 Find one small target within a 0.5 to 1.5 NM range which, lying in the bow direction, can be visually
observed and is clearly recognized on the radar screen.
(1)-2 Measure the bearing of this target from the bow direction using a compass. Let it be θc.
(1)-3 Measure the bearing of the above target in head up (HU) mode using EBL. Let it be θr.
(1)-4 Calculate the following:
θc - θr
: if θc is greater than θr
360 - ( θr - θc )
: if θr is greater than θc
The obtained value is the azimuth error of your radar at installation. If θc and θr are equal, the adjustment described below is unnecessary.
(2) Adjustment procedure
(2)-1 Select ADJUST by "common operations for CUSTOM" and select HEAD ADJ from among the
pull-down menu using the up or down cursor key. Press the "ENT" key to fix the HEAD ADJ
item.

5.6.2 Operating Instructions
5.6.2.1 Outline
The ATA detects a target from radar image signals and measures the distance from the target and its bearing
automatically. By calculating changes in the measurement results to predict the target movement, the ATA
tracks the target automatically.
The ATA calculates the CPA (closest point of approach) and the TCPA (time required for the ship to reach
the CPA) from the movement of the target toward the ship. Then comparing them to those preset, it generates
a collision alarm if both values are smaller than the preset ones.
The target bearings are calculated by (1) bearing of the target toward the ship and (2) bearing of the ship's
heading marker. Therefore, the accuracy of the data on the heading marker's bearing affects tracking performance. Tracking may become impossible if the compass is inaccurate and especially when the ship is
yawing or changing the course. These cases, however, are not caused by a malfunction of ATA.
5.6.2.2 Setting
Before using the ATA function, the settings described below are necessary.
Note: Use the ATA function in either the PPI or ALL PPI mode. Even if other modes are used, the ATA
still continues tracking though the symbols and data are not displayed on the radar.
(1) Switching the ATA function ON/OFF

5.6.2.3 Operation
(1)
Acquisition of a target
Firstly, select the target to track. Place the cursor on the target image and acquire it by using the ACQ (acquisition) function.
Press the ACQ key. When operating from the MENU, place the cursor on NAVI/ACQ and press the ENT
key.
Select the target when it is displayed clearly and no other targets are displayed around it. If other targets are
displayed around it, the ATA may track a different one.
All targets acquired by ATA are identified by the numbers, from 0 to 9. These figures will be shown in the
upper right window on the screen. A vacant column shown like "-" indicates no target being acquired.
Before starting selection, use the TGT NUM (target number) function so that "-" is highlighted.
The TGT NUM function is used to change the target numbers. The target number will not change automatically unless this function is used.
Press the TGT NUM key. When operating from the MENU, place the cursor on NAV/TGT NUM and press
the ENT key.
When ATA starts acquisition, a symbol appears at the cursor position on the screen, and the target number is
shown on the lower right side of the symbol.
(2)
Tracking the target
When the operator acquired the target by the procedure (1), ATA automatically detects the target to start
automatic tracking. As soon as stable tracking is established, a vector will be developed on the screen.
The target tracking is not relevant to the range scale in use, i.e. the tracking continues even if the range scale
is changed beyond the viewable ranges for the target.
Note: A tracked small target may be lost when the range scale is changed to shorter pulse ranges, causing
the target signal level to be decreased. This may lead to a tracking failure on the target that will become a lost
target.
(3)
Canceling target tracking
To cancel tracking, use the DEL (delete) function. The number highlighted on the upper right of the screen
will disappear. If ALL DEL (delete all) is selected, the ATA will cancel tracking of all targets.
Press the soft key if the DEL function has been set.
When operating from the MENU, place the cursor on NAVI/DEL or NAVI/ALL DEL and press the ENT
key. When the radar is set to the SY'BY mode, the ATA will cancel tracking of all targets.
(4)
Data display
When necessary, numerical data of the current tracking target can be displayed in the data display window.
Use the DATA function to display the numerical data of the number highlighted on the upper right corner of
the screen. Press the soft key if the DATA function has been set.
When operating from the MENU, place the cursor on NAVI/DATA and press the ENT key.
Items to be displayed are as follows.
Target number: TGT NO.x
The number of the target currently displayed.
Vector time:
TIME xx MIN. Setting time to display vector length. (Speed x Time=vector length)
Vector mode:
TRUE or REL Display mode of vector and data. TRUE and REL represent true and
relative speeds, respectively.
Target data:
BRG (bearing), DIST (distance), CRS (course), SPD (speed),
CPA (closest point of approach) and
TCPA (time required for the ship to reach the CPA)
State:
A collision or lost alarm will appear according to
the state of the target.
