Space-Surface Bistatic SAR topology and its impact on image formation

In a set of recent publications, an algorithm designed specifically for Space-Surface Bistatic SAR imaging has been presented. In this paper, the robustness of the proposed algorithm to the data acquisition geometry is investigated. It is assumed that, if after a pre-processing step which we refer to as "modified range compression", targets at the same range, but different cross-range, have the same or similar Doppler characteristics, then the algorithm is applicable. Some initial confirmation with experimental data is also provided.
