Sentinel-1 Radar Interferometry Applications

, 2008
The short revisit time in the ERS Tandem experiment shows the data quality reachable when the temporal coherence is high. Sentinel 1 will have a revisit time of 12 days. Using the 3 days repeat data from the ice phase of ERS1, we evaluated the improvements for distributed scatterers interferometry. Slow ground motion, visible in many successive images,
