In ARPA target handling, what does acquisition refer to?

Acquisition is the act of designating a radar echo as the target for the ARPA tracking algorithm to begin making observations. This designation starts the tracking process, allowing ARPA to establish and maintain a target track, and to compute relative motion data such as range, bearing, speed, and course, along with CPA and TCPA. It isn’t about adjusting radar sensitivity, nor is it simply locking the target’s speed, nor is it merely a later manual selection after tracking has started. Acquisition establishes the target for ARPA to observe and track.
