High-resolution wide-swath SAR processing with compressed sensing

This paper derives a signal processing method based on compressed sensing (CS) for multi-channel high-resolution wide-swath (HRWS) synthetic aperture radars (SARs) and discusses the applicability of CS for reconstructing the SAR image from undersampled SAR signals. The performance of the proposed CS reconstruction method is investigated for an exemplary HRWS SAR system and compared with the imaging performances achieved with conventional processing methods.
