Your ARPA has been tracking a target and has generated the targets course and speed. The radar did not receive a target echo on its last two scans due to the weather. What should you expect under these circumstances?

Correct Answer: Option D — The ARPA will generate data as if the target was still being tracked by radar.

When temporary radar echo loss occurs, standard ARPA algorithms temporarily extrapolate target motion using dead reckoning based on its immediately preceding track vector history.
