ARPA SENSOR DATA (2/2)
[ARPA SENSOR DATA (2/2)] displays the ARPA data that is used by manufactural
engineers. When a data number to be displayed is specified in "2. DATA NO", the data
is displayed. For instance, the data No. 0 is for the data regarding the number of input
echoes.

How to process a lost target
When the target echo under tracking is not detected in consecutive nine scannings
(preset can be changed), that target is processed as a lost target and ARPA symbol
changes accordingly. A lost target can be re-acquired if the target echo is detected
before ARPA symbol is cancelled.
Indicates the manually set drift.
When the ARPA CPU is activated, time is incremented up every
second.
Indicates "0000" when the CPU is running.
Indicates the number of auto acquisition targets.
Indicates the number of manual acquisition targets.
Indicates the number of lost targets.
Indicates the interval of inputted heading data. Antenna revolution:
Approximately 250 for 24 rpm. 12000 at the maximum when the
antenna is stopped. (60 rpm X 100)
Indicates the minimum number of echoes to be received successively
before acquisition.
Indicates the echo detection level.
Set in "[ARPA PREST] - 4.ECHO LEVEL".
