Abstract :
A space-surface bistatic SAR-GMTI algorithm is proposed here and the clutter characters are also discussed. Then a reference signal is adopted for range compression, which can make the range cell migration and Doppler centroid decreased largely. Furthermore, the clutter Doppler and phase are analysed as well as the phase difference characteristics, a phase compensation function is constructed for clutter rejection as well. At last, simulation result verifies the effectiveness of the proposed method.
