■ ATA (Automatic Tracking Aid)
By tracking automatically the target chosen by the cursor key, the closest point of approach (CPA) and the time to
closest point of approach (TCPA) limit of a own ship and a target are calculated.
ATA is the function to tell about to alarm sound, when both CPA and TCPA becomes below a setting value (the ap-
proach watch area).
The range of the target which can be registered is taken as a target with a highest luminosity level of 0.2–16 miles.
• Max. 10 targets can be plotted on the screen.
• Plot positions shall be identified by an approved symbol mark (p. 20) and associated plot number.
• The vector origin will move across the screen at a rate and direction defined by the calculated true or relative
course and speed.
• The vector will be displayed on the target.
• Display accuracy may increase by the self-ship and course change of target or acceleration, slowdown, etc.
■ ATA menu setting
Set the ATA menu items before using the ATA function.
q Push [MENU]/[ ] several times to turn the ATA
menu ON.
w Push [≈] to turn the ATA function ON.
e Push [Ú] to select the “No. DISP” to select the tar-
get identification number type which appears at the
right side of the mark. Push [Ω ≈] to select the ap-
propriate type.
• OFF: No number appears.
• SEL: Number appears by the selected mark only.
• ALL: All numbers appear by the marks.
r Push [Ú] to select “VECT”; push [Ω ≈] to select the
vector type.
• TRUE (True vector):
The predicted true motion of a target as the result of your
own ship’s direction and speed input.
• REL (Relative vector):
The predicted movement of a target relative to your own
ship.
t Push [Ú] to select “OWN VECT”; push [Ω ≈] to turn
the own vect function ON or OFF.
• OFF: For not displaying the own ship vector.
• ON: To display your own ship’s vector.
y Push [Ú] to select “ALARM”; push [Ω ≈] to turn the
alarm function ON or OFF.
• ATA alarm is emitted when both CPA and TCPA reaches
the limit.
u Push [Ú] to select the “CPA* LIMIT”; push [Ω ≈] to
set the CPA limit distance.
i Push [Ú] to select the “TCPA* LIMIT”. Push [Ω ≈]
to set the TCPA limit time.
*CPA/TCPA: Closest Point of Approach and Time to
Closest Point of Approach limit is defined by the ob-
server to a given warning when a target or targets are
close to within those limits from your own ship.
o Push [MENU]/[ ] to exit the ATA menu.

- Blind or shadow sectors may exist because of ob structions such as masts derricks or stacks an ob struction may throw either a complete or partial shadow as shown in the diagram below if a target is in a shadow sector target echoes may not appear on the screen 27
- D direction resolution 27
- D distance resolution 27
- I blind and shadow sectors 27
- I target resolution 27
- Target resolution is determined by the horizontal beam width and transmit pulse width sometimes it is difficult to detect two targets which are separated by short dis tances or which are in the same direction 27
- When tall and massive targets such as a large island are located at close range also shadowed without pro ducing any echoes this phenomenon is called blind sector it is very important to know the bearings and widths of all shadow sectors caused by your own ship s obstructions 27
- When two targets are not separated by more than the horizontal beam width they appear as one echo 27
- When two targets are not separated by more than the pulse width they appear as 1 echo 27
- When two targets are separated by more than the horizontal beam width they appear as two echoes 27
