Modifications to and Preliminary Results for the ADIT System.
Abstract
The basic system philosophy of the automatic detection and integrated tracking (ADIT) system has been reviewed. The only change to the detection system has been the addition of a merging circuit to reduce target splits. The tracking program has been modified to improve tracking performance. Included in the new tracking program are dual clutter map, new tracking filter, new correlation logic based on track quality, automatic bias correlation between radars, sector censoring capability, and a new program control. Analysis of recorded data showed that the detection system works as anticipated, detecting the targets and limiting the false alarms to a manageable number. Analysis of tracking data yielded the following conclusions: (a) detections, not tracks, should be merged, (b) tracks should be initiated with at least three detections, (c) a dual clutter map should be used, (d) the SPS-12 and SPS-39 supply an equal number of detections, (e) bias correction procedures work when the azimuth bias is less than the normal track correlation region, (f) typical errors between measured and predicted positions are 0.20 n. mi. and 0.5 deg., and (g) the turn detector enables the tracking filter to follow maneuvering targets.
