Refocusing of Moving Ships in Squint SAR Images Based on Spectrum Orthogonalization

Refocusing of Moving Ships in Squint SAR Images Based on Spectrum Orthogonalization

Moving ship refocusing is challenging because the target motion parameters are unknown. Moreover, moving ships in squint synthetic aperture radar (SAR) images obtained by the back-projection (BP) algorithm usually suffer from geometric deformation and spectrum winding. Therefore, a spectrum-orthogon...
