On the influence of sub-pixel position correction for PS localization accuracy and time series quality

Persistent Scatterer Interferometry (PSI) is a time series remote sensing technique to estimate displacements of geo-objects from the interferometric phases of selected Persistent Scatterers (PS). The relative position of a scatterer within a resolution cell causes an additional phase contribution in the observed phase, which needs to be...

Improving radar interferometry for monitoring fault-related surface deformation: Applications for the Roer Valley Graben and coal mine induced displacements in the southern Netherlands

Radar interferometry (InSAR) is a valuable tool to measure surface motion. Applying time series techniques such as Persistent Scatterer Interferometry (PSI), InSAR is able to provide surface displacements maps with mm-precision. However, InSAR can still be further optimized, e.g. by exploiting spatial characteristics of the signal of interest....
