General Five-Component Scattering Power Decomposition with Unitary Transformation (G5U) of Coherency Matrix

The polarimetric synthetic aperture radar (PolSAR) provides us with a two-by-two scattering matrix data set. ensemble averaged coherency in an imaging window derived using has all non-zero elements its three-by-three matrix. It is full 3 × that bears nine real-valued and independent parameters inside. In the proposed decomposition method, G5U, we preprocess observed [T] by two consecutive unitary transformations to become ideal form for five-component decomposition. transformation reduces seven, which best fit model expansion. We can retrieve five powers corresponding surface scattering, double bounce volume oriented dipole compound directly. These be calculated easily used display superb RBG images as never before, are further applicable calibration, classification, validation, etc.
