Abstract

An algorithm and computer software have been developed to filter out clutter in radar displays in order to clarify real tracks. Detections are generally declared valid when found to be part of a reasonable pattern of three or four detections in an eight scan history. The filtering process reduces the number of spurious reports by several orders of magnitude, providing significant improvement in distinguishing ships from waves and other sources of undesired radar reflections. The algorithm is being incorporated into radar system hardware in order to improve tracking of ships as signals are received. The method also shows promise for air tracking.
