This simulation is a function to check whether the ARPA system is
operating normally. Do not use this function except to check
ARPA operation.
Especially, avoid using this mode during actual navigation
because it will display pseudo targets on the radar screen which
may be confused with actual targets. Using this function during
actual navigation can lead to accidents.
CAUTION
5.10 ARPA SETTING
The following constants used for ARPA can be referred to and modified:
[I] SIMULATOR: Pseudo targets are generated on the radar display to check
whether the ARPA functions are operating normally.
[II] VD LEVEL: Quantizing level for the video to be input to the target
detection circuit.
[III] VECTOR CONSTANT: Constant to calculate the ARPA vectors.
[IV] GATE: Gate size to acquire and track targets.
[V] TEST VIDEO: Test video for use in checking the operation of the target
detection circuit.
