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....
