PSInSAR: detection of localized surface deformations with a modified StaMPS-algorithm

摘要

Persistent Scatterers Interferometric SAR (PSInSAR) is a powerful method for measuring surface deformations with millimeter-accuracy. Currently available algorithms are designed to detect large-scale earth movement or apply a predefined movement model. The analysis of the displacement of corner reflectors on our test area required the capability to detect localized deformation. To enable that, we modified StaMPS (Stanford Method for PS). We oppose the modified algorithm to the original algorithm, using time series of TerraSAR-X data from our test area. The finding is a distinct enhancement in the detection of localized deformation.
