Target RCS exploitations in compressive sensing for through-the-wall radar imaging.
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 the CS performance to be more robust to noise and are able to reveal target presence in noisy and cluttered environments.
