Geocoding of spaceborne SAR imagery

A rigorous model for geocoding of Spaceborne SAR Imagery is described. The model is based on actual physical parameters in the SAR signal acquisition and processing geometry and spacecraft orbital geometry. The combined model has a total of 13 parameters. The parameters can usually be computed with...
