What is the correct sequence to track a target on ARPA?

ARPA tracking starts by turning a detected radar contact into a tracked target. You first place the cursor on the target and engage Acquire or use Auto Acquire so the ARPA processor takes control of the target. The system needs several radar sweeps to gather data, filter noise, and derive a stable estimate of the target’s motion. Once enough data are collected, ARPA provides the target’s calculated course and speed, the closest point of approach (CPA) and the time to CPA (TCPA), and the vector—the predicted path. This sequence lets you see where the target is heading and when a collision risk might occur, so you can plan safe maneuvers. The other options rely on manual estimation or ignoring the automatic tracking data, which is less accurate and doesn’t update in real time. Locking onto a target and never releasing prevents the tracker from adapting to changing motion, and using manual radar while ignoring the sweeps defeats the benefits of automatic tracking.
