Sensitivity Assessment of Sentinel-1 SAR Closure Phase to Vegetation and Soil Moisture Dynamics: A Case Study for Regions in Southern France

From three coherent SAR images it is possible to estimate three interferograms. Combined in a circular way, the sum of the three interferometric phases is called the closure phase which necessarily adds up to zero on a single pixel level. However, if the interferograms are spatially averaged, phase consistency is not guaranteed. In most of the...
