Study of the impact of Polarizations for DInSAR Displacement Measures

Inhalt:
This paper has the purpose to address the problem of the choice of polarization configuration for DInSAR applications. In order to do that the standard linear polarizations (HH,VV and HV) the Hybrid polarizations (RH and RV) and the circular polarizations (RL,LL and RR) have been taken in consideration. Starting from a Quad-Pol ALOS PALSAR stack all the polarization combinations have been derived. Then processing every single stack an analysis of the results obtained on the point targets in different polarizations has been as first carried out. Then in order to asses also the potential of SAR interferometry on distributed targets the decorrelation process varying the polarization configuration has also been studied.
