Summary:
A scheme for four-component scattering power decomposition has been developed for polarimetric SAR image analysis based on the coherency matrix. The four-component consists of surface scattering, double bounce scattering, volume scattering, and helix scattering power. This decomposition scheme is applied to the L- and X-band polarimetric data acquired by the airborne Pi-SAR system and is used to monitor seasonal change of wetland area, a lake "SAKATA" in Niigata, Japan. It is shown that the four-component powers represent typical seasonal feature of vegetation near by the lake.
