Multiple Choice

How is a target "lost" indicated in ARPA, and what should you do?

When ARPA loses a tracked target, the system marks the track as Lost or Uncorrelated, signaling that automatic data association can no longer reliably follow that target. The correct response is to reestablish the track by reacquiring the target, which means manually selecting it again on the display or reinitializing the track so the system can start a fresh correlation with the current radar measurements. Doing this brings the target back under active ARPA tracking and allows you to continue calculating its course and speed. The target isn’t permanently gone, and ARPA won’t automatically substitute an unrelated target. Recovery requires your action to reacquire or reinitialize the track, after which the system can resume tracking with updated data.
