Along Track Interferometry Synthetic Aperture Radar (ATI-SAR) Techniques for Ground Moving Target Detection
Abstract
Conventional along track interferometric synthetic aperture radar, ATI-SAR, approaches can detect targets with very low radial speeds, but their false alarm rate is too high to be used in ground moving target indication radars. The report proposed a dual-threshold approach that combines the conventional interferometric phase detection and the SAR image amplitude detection in order to reduce the false alarm rate. The concept and performance of the dual-threshold approach were illustrated using the Jet Propulsion Laboratory AirSAR ATI data. A simple two-dimensional blind calibration procedure was proposed to correct the group phase shift induced by the platform's crab angle. MATLAB programs for demonstrating the proposed approach were included.
