(2) COAST Option: The lost target data is not automatically cancelled but
rather is “coasted “ and the flashing LOST TARGET symbol marks the
last position of the target. To delete the LOST TARGET symbol, track,
and target data, a manual cancel operation must be done.
CAUTION
If the target gets close to another target, the two targets
cannot be discriminated and tracking may resume on these
signals.
The operator should investigate all ARPA Alarms.
If a plot acquisition is attempted on a target close to
another plot, the new plot will be refused.
To determine accurate ARPA results, a number of past positions have to be
recorded. After acquiring a close target, the processor takes about a minute to
record enough position data to get a good, accurate speed.
More time could be required for targets more than eight miles away.
For accurate target data, accurate own ships course and
speed are required, particularly during course changes.
Sensor errors in own ships course and speed will cause
equal errors in target data. Manual speed entries can be
used, but for best performance an accurate speed log is
recommended.
A Ground Reference mode is provided to improve speed
measurements. A small, fixed, stable target is plotted to
give a zero speed reference. Target positions and own
ships position may be referred to the Reference Target.
The use of a suitable reference target will improve motion
stabilization and target data.
