Aj. Luckman, CORRECTION OF SAR IMAGERY FOR VARIATION IN PIXEL SCATTERING AREA CAUSED BY TOPOGRAPHY, IEEE transactions on geoscience and remote sensing, 36(1), 1998, pp. 344-350
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.
