| Abstract(in English) | This paper presents a new alternative three-component scattering power decomposition method by using double rotations of coherency matrix. There exist 9 real independent observation parameters in the 3 x 3 coherency matrix related to the second order statistics of polarimetric information. The alternative three-component scattering power decomposition applies to the coherency matrix and accounts for 5 parameters among 9, leaving 4 parameters un-accounted. By double rotations of the coherency matrix using unitary transformation, it is possible to reduce the number of independent parameters from 9 to 7, leaving 2 un-accounted. We used double rotations to eliminate the helix scattering source in the 4-component decomposition, resulting in new alternative 3-component decomposition. We also employed an extended volume scattering model, which discriminates the volume scattering between dipole and dihedral scattering structures caused by the cross-polarized HV component. It is found that the new decomposition results of polarimetric images are in good agreement with those of the four-component decomposition, and that vegetation and oriented urban building areas are well discriminated as compared to those resulting from the use of the existing scattering power decomposition. |
