Abstract
This study presents a fast backprojection algorithm (FBPA) for one-stationary bistatic circular synthetic aperture radar (OS-BCSAR) imaging. This method reconstructs an illuminated SAR scene in a ground plane instead of a slant-range plane. First, the imaging geometry of the OS-BCSAR is given. Then, based on the subaperture imaging model, the sampling requirements of the subimage polar grid are derived from the bandwidth angle. Finally, the implementation of the proposed FBPA is discussed. Simulation results are shown to demonstrate its validity.
