here are the following limitations on use of the target acquisition and tracking
f
unctions of ARPA:
[I] Resolution between adjacent targets and swapping during automatic
tracking
DepENTing on the particular distance and echo size, resolution between
adjacent targets during automatic tracking usually ranges somewhere
between 0.03 and 0.05 nm. If multiple targets approach each other,
resolution will become about 0.03 nm and this may cause the system to
regard them as one target and thus to swap between them or lose one o
r
more of them. Such swapping or loss of targets may also occur if the
target image is affected by rain or snow clutter, sea clutter or if the target
moves close to land.
[II] Intensity of echoes and the tracking function
The intensity of echoes and the tracking function are correlated, and thus
the target will be lost if no echoes are detected for six consecutive scans.
Therefore, if there is a lost target, radar gain must be increased to improve
target detection. If, however, radar gain is increased too much, sea clutte
r
or other noise may be mistakenly detected and tracked as a target, and a
false alarm may result. In such cases, do not apply strong impact to the
touch panel, trackball or gain, because doing so may cause a malfunction.
[III] Adverse effects of error sources on automatic tracking
To execute accurate tracking, it is necessary to accurately adjust the
[GAIN], [SEA] and [RAIN] controls of the radar so that the target to be
acquired and tracked is clearly displayed. Inappropriate settings for these
controls will reduce the reliability and accuracy of automatic tracking.
