The project deals with the use of images from radar satellites with short and regular revisiting time for monitoring and measuring sliding phenomena and for studying terrain slope instabilities.
At present RADARSAT is the only SAR satellite system that guarantees the systematic and regular images acquisition. The project objectives are the following: to verify the theoretically predicted potentialities offered by the RADARSAT short and regular revisiting time; to combine digital terrain models (DTM) and ground displacement SAR measurements; to develop tools for estimating highly non-linear motion mainly for irregular sliding motion (typically dependent on the rain rate). The research unit of the Politecnico of Milano (POLIMI) is in charge of selecting and processing the most suitable satellite radar data for analyzing the sliding motion of the sites of interest selected by the Coordinator and the other research units of the project. The project is in progress.
