Track Initiation Techniques in a Dense Detection Environment
Abstract
In a dense detection environment, current track-while-scan algorithms will inevitably introduce false tracks when processing is performed on a scan- by-scan basis. Four track-initiation techniques are discussed and evaluated against three typical raid scenarios. Three of the techniques are within the current state of the art. The fourth technique is the maximum likelihood solution for track initiation which involves enormous computational requirements. This technique is included to provide a standard of comparison for the other techniques. The other three techniques are the conventional nearest neighbor correlator with an a priori velocity, a raid initiator in which firm tracks are removed from a raid as soon as a good velocity estimate is obtained, and a raid tracker in which individual tracks are operated on as a raid while the estimates of raid velocity and size are refined. The preferred technique would seem to be the raid tracker.
