Because real data of scattering interference for SAR are not available, a physical model of scattering interference for SAR is presented, and the scenario scatterer distribution characteristics are analyzed in this paper. The simulation results demonstrate that the scatterer incident angles for very diffuse scenario and moderately diffuse scenario cover the whole beam of SAR in azimuth, and then the spatial filtering algorithms are useless. However, numbers of correlated scatterer pairs increase when more samples are employed for the moderately diffuse scenario. Thus, space fast-time adaptive filter can be used to suppress scattering interference for moderately diffuse scenario.
