Summary:
This paper considers a decomposition technique of polarimetric synthetic aperture radar’s covariance matrix which considers the azimuth rotation of each scattering component. This type technique decomposes a covariance matrix into surface, double-bounce and volume scattering components. Although the past techniques assume that the scattering components have the reflection symmetry property, there is a possibility that the urban and mountain areas do not satisfy it due to the azimuth rotation. Thus, we propose a modified decomposition technique dealing with a compensation of the rotation. It is shown that the proposed method can remove influences of rotation from the decomposition result and the polarization ratios between HH and VV in surface and double-bounce scattering components can be estimated without an assumption that one of them becomes 1 or -1.
