Abstract：A new imaging method is proposed for multi-aperture wide-swath Synthetic Aperture Radar (SAR) in this paper. The imaging algorithm is proved theoretically, and the weighting matrix is proved to be in good condition. The computational complexity of the imaging algorithm is analyzed. The Signal-to-Noise Ratio (SNR) of this kind of multi-aperture wide-swath SAR is discussed. Finally, the simulation result is presented.
