Summary
PSInSAR techniques are extensions of conventional InSAR aimed at addressing the problems caused by decorrelation and atmospheric delay. the PSInSAR (Permanent Scatterers InSAR), developed by Ferretti et al.,involves the simultaneous processing of multiple SAR acquisitions over the same area to allow for the correction of uncorrelated phase noise terms and hence, reduce errors associated with the deformation estimates.

In this research, we focus our attention on using PSInSAR techniques with TerraSAR data for ground deformation monitoring in Pearl River Delta, thus analysing the ground instability and monitoring the activity of mining of groundwater. The research will help to gain better insights into the deformation and its evolution in this region and to improve the overall accuracy and reliability of the InSAR technology.
