Range Doppler algorithm for bistatic missile-borne forward-looking SAR

Side-looking SAR cannot image targets in flight direction. Introduced here is the bistatic missile-borne forward-looking SAR system, as an efficient approach to forward-looking SAR imaging. According to the spatial geometry and the model of echo signal, the signal spectrum derived by the method of series reversion, the phase compensation factors and the realized step of the proposed algorithm are given. Several simulation and processing results are presented to demonstrate the validity of the proposed algorithm.
