Abstract

In this paper, we present a modified imaging algorithm and the target-location method for the general case of bistatic synthetic aperture radar (BiSAR), when the transmitter and receiver move along nonparallel trajectories with different velocities. As a step to a numerically efficient processor, the basic linear range-Doppler (LRD) algorithm is firstly generalized from the monostatic SAR to BiSAR imaging, which also enable the ground-target location processing to be feasible. We show that, the LRD algorithm combined with the Newton iteration method could offer a precision and efficient approach by solving the double hyperbolic equation of the range Doppler history of the general BiSAR system. Simulation results of airborne BiSAR imaging and location of stationary ground point-targets are given to demonstrate the effectiveness of the proposed algorithm.
