摘要：

The radiometric correction of synthetic aperture radar (SAR) imagery for topographically induced changes in the pixel scattering area is examined, The relative significance of ground slope in the range and azimuth directions is compared, and a widely used correction factor, based on the sin of the local radar incidence angle, is shown to be sufficiently accurate. The importance of performing this correction in slant range, rather than ground range, is demonstrated.
