Abstract
Circular synthetic aperture radar (CSAR) has become of particular interest to the SAR community. According to the isotropic targets, the spectrum of which is ring-shaped, therefore the corresponding point spread function (PSF) is related to Bessel Function, and the sidelobe level is higher. In this paper, a novel sidelobe reduction method based on the image processing is proposed. Simulation test proved that this method could express the sidelobe of CSAR from −8 dB to −16 dB without the expansion of mainlobe.
