Abstract: The phase coherence factor (PCF) is revised according to stepped frequency signal imaging radar, adding additional phase diversity in frequency domain. Then, it is applied to through-the-wall moving target indication processing for side and grating lobe artifacts mitigation. Experimental results show that PCF weighting approach can suppress both side and grating lobe artifacts effectively for through-the-wall images.
