What is the purpose of track correlation in ARPA?

Track correlation in ARPA is about data association across radar scans to keep a single target identified over time. The system uses the last known position, speed, and course of a detected target to predict where it should appear in the next sweep. It then looks for a new radar detection near that predicted location and with compatible motion. When a match is found, the new data is linked to the existing track and the track is updated; if no good match is found, ARPA may start a new track or discard an old one. This process creates a continuous, coherent path for the target across scans, helps filter out clutter, and improves the accuracy of motion prediction for safe navigation. It isn’t about calibrating range, identifying vessel type, or predicting weather.
