Abstract

This paper is devoted to propose some new efficient indicators in comparison of syn- thetic aperture radar (SAR) imagine performance between matching filter (MF) and compressed sensing (CS). Generally, SAR utilizes matched filtering (MF) technique to improve resolution, whereas CS is a newly developed technology for sparse or compressible signal which can be ap- plied to SAR imaging to achieve super-resolution images. Based on the theory derivation, the paper compares CS with MF in several aspects, such as resolution and SNR, several new indi- cators were also given to evaluate imaging performance because of new features caused by CS processing, such as microscopic and macroscopic resolution and group spread function (GSF). The comparison results are discussed and verified by data simulation.
