Detection, Tracking and Geo-location of Moving Targets in Airborne Radar Data using a DPCA GMTI Technique

A dual-channel displaced phase center antenna (DPCA) ground moving target indication (GMTI) algorithm was developed and implemented on radar data recorded with an airborne synthetic aperture radar (SAR) system. This paper discusses the implemented technique and shows that it is able to suppress clutter and detect ground moving targets. An Alpha-Beta tracking algorithm was also implemented to reduce the false detections by tracking and confirming the detected ground moving targets over several coherent processing intervals (CPI) as the radar flew past the scene. The detected and confirmed targets were also geo-located on Google Earth with an implemented geo-location algorithm.
