Abstract
The radiometric correction of synthetic aperture radar (SAR) imagery f or topographically induced changes in the pixel scattering area is exa mined, The relative significance of ground slope in the range and azim uth directions is compared, and a widely used correction factor, based on the sin of the local radar incidence angle, is shown to be suffici ently accurate. The importance of performing this correction in slant range, rather than ground range, is demonstrated.
