Picture 6
The illustration shows the test picture in the
following case:
- Range: 24 NM
- Gain: Maximum
Each of the broad rings consists of rings
arranged inside each other without gaps. If the
gain is reduced, the intensity of these rings
decreases, beginning with the inner ring.
ARPA Function Test
By means of the ARPA function test, the overall performance of the ARPA can be assessed. This should
be done periodically.
Set Range to 6 NM. In the list, select ARPA.
After the start, this picture appears. The indi-
vidual echoes displayed are synthetic targets:
- It must be possible to acquire them
manually.
- When the acquisition / guard zone is
placed over one or more targets, auto-
matic acquisition must take place,
together with the associated symbols and
alarms. The targets must be tracked
automatically.
- All targets travel along with your own
ship. Therefore, their true courses and
true speeds must be the same as your
own ship’s course and speed.
