The Permanent Scatterers (PSs) SAR Interferometry has become an operational tool in the context of spaceborne SAR interferometry for monitoring surface deformation with millimetric accuracy. In this contribution we presented a case study in Xi'an city for land subsidence monitoring and ground fissures detection by using PS InSAR. We applied a linear regression model to retrieval land subsidence velocity...
Spaceborne SAR interferometry (InSAR) is a well known microwave remote sensing technique which has been applied for topography mapping and ground motion monitoring by exploiting phase difference from SAR data acquisition with relevant large spatial scale and high precision. The developed Permanent Scatterers Interferometry (PSI) is a further step of InSAR technique which offers a convenient processing...
