Identification and analysis of point scatterers in time series InSAR

In this study methods are developed for improved analysis and processing of PSI data. PSI, or radar interferometry, makes it possible to use satellite radar images to measure deformation of the Earth’s surface and objects on it with millimetre accuracy. However, interpretation of the measurements and identifying the actually measured objects is...

Improving Persistent Scatterer Interferometry Results for Deformation Monitoring: Case study on the Gardanne mining site

The persistent scatterer interferometry (PSI) is a relatively new technique in radar interferometry which has matured, within a last decade, to a practical technique for measuring the deformation of the Earth’s surface. PSI overcomes the main limitations of conventional InSAR methods by identifying radar targets, called persistent scatterers (PS...
