N2 - Spaceborne Synthetic Aperture Radar (SAR) systems usually operate over land in complex scanning modes such as ScanSAR or TOPSAR that can achieve wide swath coverage in a single pass of the satellite at the cost of degraded cross-range resolution. This work demonstrates the feasibility to produce bistatic radar images using a SAR satellite as emitter of opportunity and a stationary ground-based receiver with a 5-fold increase in cross-range resolution in TOPSAR mode. A Maximum A Posteriori-based image reconstruction method is validated using real measurements from the European Space Agency's satellite Sentinel-1A.
