A geocoding method for SAR image based on Triangulated Irregular Network (TIN) lookup table is proposed in this paper. Firstly, TIN DEM is generated from Grid DEM. Then, each node in TIN DEM is geocoded by Range-Doppler model to produce a TIN lookup table. Finally, geocoded image is resampled by TIN...
