SummaryDeformation analysis from spaceborne SAR data isa maturing technique with a broad spectrum of applications from giving scientistsunique possibilities of studying dynamics of the earth’s surface to monitoringof hazards from volcanoes or landslides, monitoring of infrastructure orsteering exploitation of carbohydrate reservoirs. The latest algorithms userefined statistical methods in order to group pixels of same scatteringbehavior and extracting a common phase history, which increases the number ofpixels where meaningful information is available considerably while preservingresolution at the same time. Technical details of these algorithms and how todesign them in an optimal way is not well documented up to now and deservesdeeper investigations. In the course of this project we are performing athorough study e.g. on critical steps as grouping of pixels and on preselectingDS candidates (DSC) in order to reduce the considerable computational load. DS are predominately found in sparsely vegetated,dry terrain with large number of at least medium size scatterers. The Etnavolcano in Sicily seems well suited for this purpose. Former investigations onthis scene have demonstrated the big increase in high quality information whenincluding DS in the analysis. As extensively monitored phenomenon and one ofthe Geohazard Supersites ground truth is available. Therefore we apply for The project is funded as part of a projectrunning at IOSB until the end of 2016 and is expected to be continued afterwards.
