Abstract :
In the last decade, the three-component polarimetric scattering decomposition by Freeman and Durden has stimulated research and applications in model-based decompositions. In this paper, we will review recent advances in the scattering models, focusing on the negative power problem and its mitigation, the problem of the reflection symmetry assumption, and the effect of orientation angle compensation. An extended decomposition based on the extended Bragg model is also proposed. Polarimetric SAR images illustrate our approach.
