Ground Moving Target Detection Based on Region-correlation Ratio Weighted of DPCA

Displaced phase center antenna (DPCA) and along-track interferometry (ATI) are two classical techniques used to determine synthetic aperture radar-ground moving target indication (SAR-GMTI) field. According to the research from now, conventional DPCA is superior to ATI[1],[2]. But, even the conventional DPCA is not all that could be desired. This paper proposes the algorithm called region-correlation ratio weighted of DPCA (WDPCA) algorithm. We introduce a novel concept of region-correlation ratio weighted so that the proposed algorithm promotes the detection performance compared with conventional DPCA. Some numerical experiment are also provided to prove the new algorithm has a better performance than the conventional algorithm.
