Abstract

In this paper, a fast time-domain imaging method called the fast backprojection algorithm (FBPA) is proposed for the one-stationary bistatic forward-looking synthetic aperture radar (OSBFSAR). First, the backprojection (BP) algorithm of the OSBFSAR is introduced. Then, the FBPA of the OSBFSAR based on the subaperture BP imaging is provided, and the sampling requirements of the polar subimage grid are derived from the bandwidth angle. Finally, the implementation of the proposed FBPA is discussed. Simulation results are shown to prove the validity of the proposed algorithm.
