Interferometric Investigations with the Sentinel-1 Constellation and Results

The contribution focuses on the current status of the ESA study entitled “INSARAP Sentinel-1 Constellation Study”, and investigates the interferometric performance of the S1A/S1B units. General aspects like the interferometric compatibility in terms of common range and Doppler bandwidth and the burst synchronization will be addressed. Besides the first interferometric results with both units, time series results over the pilot sites combining both satellites will be also shown. In addition, advanced investigations concerning the exploitation of the overlap areas, the estimation and correction of ionospheric artefacts, or processing approaches for fast moving scenarios (e.g., glaciers) will be presented.
