Abstract

The strong target contamination has a great influence on the performance of the conventional clutter suppression method. In this paper, a robust approach to clutter suppression and ground moving target detection has been proposed for multi-channel SAR system. Firstly, the modulus normalized vector corresponding to the pixel data vector is constructed and its covariance matrix has been formed. Secondly, the ground clutter is suppressed using the new adaptive clutter suppression weight. Lastly, target detection and localization are carried out. The effectiveness and robustness of the proposed approach are confirmed by performance analysis and real measured data processing.
