- W4313144530 abstract "Sidelobe suppression is an issue of interest in Synthetic Aperture Radar (SAR) imaging. Sidelobes of strong targets may cover weak targets in its neighborhood and reduce image quality. Various methods have been used to suppress sidelobes. However, these methods may not work well because they do not consider the scintillation of the targets, i.e., a target has different scattering coefficients when it is illuminated from different directions by the radar beam. This paper proposes a new method to suppress sidelobes adaptively, especially in azimuth. A Wiener filter is used to whiten the Doppler spectrum, and then a Gaussian window is used to suppress sidelobes. This method considers the scintillation of the targets and thus has a better performance than traditional methods." @default.
