Extended Polar Format Algorithm for Large-Scene High-Resolution WAS-SAR Imaging

Extended Polar Format Algorithm for Large-Scene High-Resolution WAS-SAR Imaging

The polar format algorithm (PFA) is a frequency-domain algorithm with high computational efficiency especially for the high resolution imaging applications in wide-angle staring synthetic aperture radar (WAS-SAR). Because of the image distortion and defocus caused by plane wave assumption, the effec...
