Potential use of Polarimetric Information for Terrain Morphological Change Detection Including Atmospheric Phase Screen Compensation Effect in Ground-Based Dinsar Application

In this study, we investigated the potential use of polarimetric information to detect the land morphological changes without APS compensation. We proposed to use the APS independent descriptor and the covariance matrix likelihood ratio for APS. We validated the proposed technique by selecting the soil accumulated zone for a land elevation as a part of the restoration work at the landslide affected slope. The 24-hour processed time-series result reveals that both the APS independent descriptor and the likelihood-ratio are in agreement with the APS-compensated DInSAR result. The proposed idea shows the reasonable capability of detecting the land morphological change without APS compensation.
