Paper Abstract

This paper proposes a novel dual-SAR detector based on the joint metric of interferogram's magnitude and phase for slow ground-moving targets. Motivated by the difference of backscattering properties between slow moving targets and stationary clutter in the SAR image, we devise a new metric for slow ground-moving target detection by combining the interferogram's magnitude and transformed phase. By using simulated data, we demonstrate that this detector can help detect slow moving vehicles within severe ground clutter. Compared to the traditional Displaced Phase Center Antenna (DPCA) and Along-track Interferometry (ATI), this detector performs better because of its higher stabilization, wider range of detection velocity, lower probability of false alarm and higher detection probability.
