Abstract：Synthetic Aperture Radar (SAR) with multiple antennas can realize High-Resolution Wide-Swath (HRWS) imaging，improve Signal to Noise Ratio (SNR) and improve ambiguity suppression for Moving Target Indication (MTI). This paper proposes an algorithm can realize HRWS imaging based on conversion bi-static data into mono-static data. The algorithm can correct phase according to velocity fluctuation of platform change. Furthermore the algorithm has high efficiency, for azimuth data need only one time FFT operation. Performance analysis and computer simulation are presented to illustrate the validity of the algorithm.
