Title of the thesis:Ground Stability Monitoring of Selected Sites in Slovakia Using InSAR Technology
Summary:The integrated use of multiple Synthetic Aperture Radar (SAR) platforms for the deformation monitoring via satellite radar interferometry offers several perspectives for investigation of the ground motion and behaviour of structures and infrastructures under varying or hazardous environment. Spanning almost 25 years of spaceborne radar observations, this study aims to perform classical PSInSAR (Persistent Scatterer Interferometric Synthetic Aperture Radar) analysis incorporating measurements of ERS, Envisat, Sentinel-1, Radarsat-2 and TerraSAR-X satellites. The results from the processing of different satellite data over selected parts of Slovakia are presented, focusing on the description of characteristics associated with the specifics of every satellite platform in use and purpose of monitoring. The areas of interest are selected specifically for the region of Slovakia and prior to the main problems that are associated with its territory. The InSAR technology is applied for the deformation monitoring of: i) urban areas and ii) landsliding or undermined areas. The main part of the work is dedicated to the data-mining approach for post-processing of multitemporal InSAR results. The algorithm has been developed as a base platform for the deeper exploitation of low-coherent areas and supports solution of the problems that are associated with InSAR deformation monitoring. The discussion over technical feasibility of InSAR deformation monitoring is accompanied by the outline of possible future needs for the utilisation of the wealth source of information provided by the satellite radar imagery.
Key words:landslides, InSAR, deformation monitoring
