The paper discusses the possibilities to reconstruct an illuminated Synthetic Aperture Radar (SAR) scene in a ground plane instead of a slant-range plane using Fast Backprojection (FBP) algorithm. Hence, two methods to reconstruct a SAR scene in a ground plane are introduced in this paper. The methods are then considered to be extended for bistatic cases where the formation of a SAR scene in a ground plane is highly recommended. The proposals are examined with simulated SAR data and the simulation results indicate that rebuilding a SAR scene in a ground plane using FBP is possible.
