Detection performance of moving target with compressive sensing via dual-channel spaceborne SAR

摘要

Based on the fact that the moving targets are sparse in spatial domain after clutter suppression, we present a novel approach for the indication of moving targets with compressive sensing from dual-channel spaceborne SAR sparse raw data. Moreover, the detection performance measures in terms of GMTI are different from the existing ones for CS. In this paper, the probability of detection (PD)-curves are presented to analyze the detection performance of different CS reconstruction approaches. Not only the experiments with the dual-channel spaceborne SAR simulated and real data but also the detection performance of the proposed method is analyzed in this paper. The result shows that this method is more effective.
