  • Scattering interference will result in large regions being blurred while forming a SAR image, and Space Fast-time Adaptive Processing (Fast time STAP) can be utilized to mitigate its influence. A scattering interference mitigation method based on Cross Spectral Metric (CSM) for Multi-channel SAR (MSAR) is presented in this paper, and the cross spectrum of the interference plus noise covariance matrix is analyzed. Also, the interference mitigation performance of the new method is analyzed, and is compared with the performance of the method based on Principal Component Analysis (PCA). The simulation results demonstrate that CSM performs better than PCA in scattering interference mitigation.
