Abstract：A Fast Back Projection (FBP) algorithm for spotlight mode Bistatic Synthetic Aperture Radar (Bi-SAR) was presented. Sync channel signal from land receiver was taken as matched filter for echo signal in the phase of range compression, and the secondary phase calibration decreased the approximation error effects for FBP algorithm in the phase of azimuth compression. Computational complexity of this algorithm was O(N2.5 ). In addition, this algorithm was validated on Graphic Processing Unit (GPU) by simulation data and measured data.
