  • The bistatic configuration, when transmitter and receiver move along nonparallel tracks with unequal velocities, is called the general bistatic Synthetic Aperture Radar (SAR). This kind of bistatic SAR system has the potential for various applications. In this paper, it is shown that, for the general bistatic SAR with a long baseline, it is hard to convert the bistatic SAR data into a monostatic one for which the monostatic processor can be employed. Then, a Range Migration Algorithm (RMA) based on series reversion and numerical computation is presented. Finally, the accuracy of the proposed approach is verified with a simulation. The analysis and the simulation result show that this algorithm can be applied to the general bistatic case with a long baseline and a high squint angle.
