Compressive sensing (CS)-based multipath exploitation has been successfully applied to stationary indoor scenes in through-the-wall radar imaging (TWRI). The benefits of using significantly reduced data are also desirable for moving targets. Hence, we bring CS based multipath exploitation to the non-stationary target domain and are able to treat moving and stationary targets simultaneously. In general,...
In this paper, target radar cross-section (RCS) is utilized to improve the performance of compressive sensing (CS) when applied to sensing through wall based on RF modality. Using step-frequency SAR imaging, it is shown that the selection of frequencies emitted at each antenna position of the SAR system can benefit from a priori knowledge of the target RCS. Frequencies with high target response allow...
