Abstract
The intent of this paper is to propose the method of dual-aspect radiometric and geometric terrain correction to solve the two problems, radiometric variation and radiometric information loss. Firstly, the radiometric terrain correction method which considered gamma naught based image plane as measure of backscattering coefficient, which can correct radiometric variation of PolSAR images at the facing slope and back slope areas. Secondly, two color PolSAR images with dual opposite viewing angle are mutually fused by replacing invalid radiometric value with valid radiometric value from the opposite viewing image, which can generate integral radiometric information for orthophoto creation.
