Reduction of the tracking loop bandwidth is adaptive in clutter scene

摘要

A tracking system and method that achieves track loop bandwidth reduction and analyzes scene information from an expanded area around a tracked target. Objects in the scene that may interfere with the target and cause degraded tracking performance are tracked (12) to determine the level of likely perturbation of a primary tracker (11) due to interference. The present invention predicts the time (37) at which interference due to clutter objects will occur and the estimated time duration of the interference. The present invention uses this information to determine and variably adjust (13) the bandwidth of a track loop to prevent track loss while detecting and tracking maneuvers of the target. IMAGE
