RESOLVING RADAR ANGLE AMBIGUITIES USING A MULTIPLE HYPOTHESIS TRACKER

摘要

Radar system that utilizes Multiple Hypothesis Tracker (MHT) to resolve angle ambiguities, from a series of dwells with ambiguous detections over time. The system receives first and second observation, forms radar tracks and ambiguous angle detections using unfolding data at each of the ambiguous angle detections, scores the radar tracks to determine a best hypothesis of tracks, where a hypothesis for the MHT is formed by collecting compatible tracks into the hypothesis and computing probabilities of the hypothesis by using the score of each radar track in said hypothesis, and compares the scores of all the radar tracks originating from the first observation data to determine whether one of the scores of the radar tracks exceeds the scores of all other radar tracks originating from the same first observation data by a predetermined range.
