Abstract
In mapping non-flatregions of the earth using airborne Synthetic Aperture Radar, terrain height variations cause two problems in radiometric calibration: the first being that the local incidence angle for any pixel may vary from that given by the flat (or curved) earth assumption; the second that the wrong elevation angle may be usedin correcting for the radiometric variation of the antenna pattern. In this paper, we show how the latter problem may be solved by using polarimetric SAR data in a novel fashion to determine the elevation angle and thus the height at the different parts of the image.
