A Novel High-Resolution Wide-Swath SAR Imaging Algorithm
Based on the theory of compressive sensing, in this chapter a novel high-resolution and wide-swath Scan SAR imaging algorithm is proposed. The proposed algorithm consists in range compression by the traditional matching filter method, range cell migration correction and the cross range compression by compressive sensing technique. The comparison between the traditional range-Doppler algorithm and the proposed method shows that the proposed method is suitable for high resolution wide swath imaging based on Scan SAR.
