Imaging algorithm for missile-borne SAR with diving acceleration based on series reversion

In the missile-borne SAR working mode,there will be a strong coupling between range signal and azimuth signal.The echo model of the missile-borne SAR is established by using a fourth order range model,and the two-dimensional point target spectrum is derived by the method of series reversion,followed the corresponding range and azimuth match filtering functions are provided for motion compensation.The point target simulation results are presented to demonstrate the accuracy and validity of the proposed algorithm.
