SummaryOur goal is to reduce latency time and increase the sampling rate by using TerraSAR-X data with multiple incidence angles with higher temporal resolution by volcano monitoring, about 4 to 5 observations in the 11 day repeat cycle. Using multiple incidence angles requires substantial new method developments, i.e. incorporation of 3D motion model assimilation into the persistent scatterer estimation process. Also natural objects (rocks etc.) shall be exploited as persistent scatterers. Another goal is to discriminate sudden volcanic motion events from long term trends or rest periods. New statistical estimation processes based on Bayesian hypotheses tests will be developed for this purpose. Additionally to the fast motion analysis with TerraSAR-X, ALOS L-band data will be used in order to improve the two dimensional coverage even in vegetated areas. The decorrelation at different wavelengths (X, C, L Band) will be compared, analyzed and modelled. The results of the deformation analysis will be ingested into the project data base (TUM & DLR) from where they will be read and incorporated into geophysical models (Uni. Potsdam & Hamburg) in order to improve early warning. If ground based SAR observations of TU Darmstadt are available, those will be compared to the results and, if possible, fused into a joint model. The work is closely related to the European GMES project Terrafirma, where DLR is managing responsible for quality control and validation of new InSAR algorithms for the subsidence monitoring of European cities.
