Analysis of Singular-point Generating Mechanisms Based on the Correlations among the Parameters in Coherency Matrix and Those in the Optimized Scattering-mechanism Vector in PolInSAR

摘要

We investigate the relationship between the changes in phase and those in polarization in polarimetric interferometric synthetic aperture radar (PolInSAR) to elucidate the generation mechanisms of singular points (SPs). The results of the analysis show that there is a correlation between the parameters in the scattering mechanism vector optimized to maximize the interferometric coherence and those in the Pauli coherency matrix. It means that there is a correlation between the parameters of the phase compensation and the parameters of polarization. That is, the changes in phase and those in polarization originate from an indentical phenomenon, namely, scattering itself. It also means that the polarization parameters can be vised for compensation of SPs.
