High resolution SAR-Signatures, Time Series and 3D Analysis for Safeguards Verification Activities

Abstract

This talk reports on ongoing activities under the German Support Programme to investigate and convey the use of high resolution TerraSAR-X SAR for safeguards’ purposes. For the study, an actual nuclear facility with access to in-situ data (Forschungszentrum Jülich) has been selected. Different time series of TerraSAR-X images with different acquisition parameters (Spotlight, Stripmap, Dual-Pol, TanDEM-X) are acquired over this site and also high resolution optical data could be acquired for comparison. Different processing techniques are investigated ranging in complexity from single image interpretation over multi-image change detection to interferometric analysis and even persistent scatterer interferometry (PSI). The co-registered data stack generated in the course of the study reveals the individual advantages of radar and optical images and also the potential in combining both data sets.
