Abstract :
This paper presents a bistatic focusing solution for bistatic forward-looking SAR (BFL-SAR) in translational invariant case. The approach is based on the spectrum which is derived by time domain equivalency. According to strong range cell migration (RCM) of BFL-SAR, high order phase terms compensation is added to the algorithm. Simulation results show that the extended SIFFT algorithm can focus the BFL-SAR signal.
