摘要

A high resolution wide swath (HRWS) mono-static synthetic aperture radar imaging method is proposed in this paper. In this method, we use a random scanning method to adjust the direction of the radar beam, effectively broadening the width of the imaging scene. And then, we use the compressed sensing technique to process the random sampling data and reconstruct the high-resolution imaging results of sub-scenes. Finally, the SAR image of the whole scene can be obtained by sub-images splicing. Simulation results verify the effectiveness of the proposed method.
