This letter presents a novel change detection technique based on stepped-frequency continuous-wave synthetic aperture radar interferometry to detect human beings in motion inside a building. The proposed approach to moving-target indication consists of radar image formation, noncoherent energy change detection, and interferometric phase detection. Experimental results demonstrated that the proposed approach can dramatically reduce false alarms compared with a conventional noncoherent change detection approach.
