Abstract

This paper introduces a new distributed SAR processing based on fractional Fourier transform for ground moving targets imaging. According to the analysis of the minimum mean-squared error, the distributed SAR representation is given. The multi-channel Doppler imaging used adapting coefficient to handle azimuth domain processing. Compared with the traditional approaches, it can achieve a better result of clutter cancellation by using optimal beamforming in the fractional Fourier domain. The effectiveness of this method has been tested through simulation
