Relating polarimetric SAR image texture to the scattering entropy

In our previous paper, an extension of the polarimetric product model to explain polarimetric variation of texture in high-resolution synthetic aperture radar (SAR) images has been proposed. The extended model suggests that existence of multiple scattering mechanisms provides the polarimetric texture diversity. In this paper, the polarimetric target decomposition theorem is utilized to validate the model. The entropy derived from the target decomposition is a useful sign of scattering randomness. The results of data analyses reveal that there is significant correlation between the variation of the K-distribution´s order parameters and the entropy value.
