N2 - A contradiction between wide swath and high spatial resolution exists in synthetic aperture radar (SAR) imaging processing. Displaced phase centers multiple azimuth beams (DPC-MAB) system can make a tradeoff between them, but it arises non-uniform sampling in the azimuth direction. In this paper, a novel reconstruction method associated with the fractional Fourier transform is proposed, which has better performance compared with the traditional one. Moreover, it can reconstruct undersampled signal successfully while the traditional method fails. Simulations verify the efficiency of the proposed method.
