英文摘要	Based on a quantitative study of the incident angle effect of a wide-swath synthetic aperture radar (SAR) image, this paper proposes a class-based correction method for such an effect. The method achieves sampling by using watershed segmentation and regional labeling technology as well as a class-based radiation correction of land-cover backscatter values based on the cosine Lamberts law estimated through linear regression. Experimental results of the Envisat Advanced SAR (C-band horizontal-transmitting, horizontal-receiving polarization) data show that an incident angle effect is exerted on radar backscatter; the higher the moisture content of the land-cover type is, the more obvious the incident angle effect is. The correction of incident angle effect with this proposed algorithm is better than order cosine correction.
