SYSTEM AND METHOD FOR DETECTION AND FEATURE EXTRACTION IN PASSIVE COHERENT LOCATION APPLICATIONS

摘要

A system and method for detection and feature extraction in a passive coherent location system is disclosed. During a coherent processing interval, detections and target parameters for targets. The system forms and ambiguity surface that has ambiguity surface data or the coherent processing interval. Bins from a previous ambiguity surface are associated with the ambiguity data. New bins are identified for new target echoes within the ambiguity surface. Peak detections are formed from the bins. The peak detections correlate to the target echoes of the coherent processing interval. Target parameters for the targets are estimated from the peak detections.
