Clutter suppression and imaging of non-cooperative moving targets via virtual multichannel SAR

Abstract

Clutter suppression is needed to detect slow moving ground targets within SAR scenes and this becomes possible when sufficient spatial degrees of freedom are available. In this paper a processing scheme that exploits a high PRF single channel SAR system to emulate a multichannel SAR system is presented. A signal model of the virtual M-SAR is presented and the effectiveness of the proposed scheme is demonstrated on simulated data.
