In this paper, a fast numerical Range Migration Algorithm (RMA) is proposed for GPS signal based continuous wave spaceborne-airborne bistatic SAR. A two dimentional precise analytic expression in frequency domain of system response signal is deduced by using approach of instantaneous Doppler wavenumber, and the match function and interpolation function of the proposed algorithm can be obtained numerically. The proposed algorithm has the characteristics of fast speed and high precision of RMA. In addition, it also has the same wide application range compared with Back Projection (BP) algorithm. %K Global Positioning System(GPS) %K Bistatic Synthetic Aperture Radar (BiSAR) %K Range Mitigation Algorithm(RMA)
