Sentinel-1 TOPS interferometry for ice flow mapping
A major challenge in applying Sentinel-1 interferometry to measure ice sheet velocity is the significant horizontal scene motion associated with ice flow, which can cause phase discontinuities at burst boundaries in the TOPS interferograms, leading to phase unwrapping problems. We present a simple m...
