| Abstract: | Stereo synthetic aperture radar (SAR) geolocation model is an important geolocation model for spaceborne SAR. However, the
error of stereo SAR geolocation model has not been analyzed in detail. This paper deduced the geolocation error formulas of
the stereo SAR geolocation model and then compared the geolocation error with range Doppler (RD) geolocation model. Through
computer simulation, we could get the advantages and disadvantages of the stereo SAR geolocation model. |
