The Added-Value of TOPSAR Coherence Tracking for Sentinel-1 Interferometry Over Ice Shelves
peer reviewed Feature tracking has long been used as a technique to infer bidimensional displacement maps by locally maximizing the incoherent or coherent cross correlation of coregistered SAR images. Coherence tracking is based on the latter technique. Exploiting the phase information, the method t...
