An experimental study on image based multi-channel SAR-GMTI algorithm

The authors have recently proposed an algorithm for target detection and velocity estimation for multi-channel SAR-GMTI (Synthetic Aperture Radar - Ground Moving Target Indication) systems [1]. The proposed algorithm is a combination of extensions of DPCA (Displaced Phase Center Antenna) and ATI (Along Track Interferometry). In this paper, we report some results obtained from an airborne three-channel SAR experiment to show the potentials of the proposed algorithms.
