Survey of radar Automatic Detection and Tracking (ADT)

This report surveys the state of the art of automatic detection and tracking for radars. This subject is reviewed under the three subtopics of (1) noncoherent integration techniques, (2) false alarm control, and (3) tracking system. In the area of noncoherent detection, various integrators such as the moving window, feedback integrator, two-pole filter, binary integrator, and batch processor are discussed. False alarms are controlled by using either adaptive thresholding, nonparametric detectors, or clutter maps. A general outline of a track-while-scan systems is given and then a discussion of the tracking filter, maneuver-following logic, track initiation, and correlation logic is presented. Finally, methods of integrating data from both colocated and multisite radars are discussed.
