Measurement of Wind Speed on the Antarctic Peninsula Using ERS-SAR Tandem Interferometry
The relation between interferometric coherence and meteorological parameters at the snow surface is investigated for a study area on the Antarctic Peninsula. Five ERS tandem pairs have been processed to provide image sets of ERS-1/2 backscatter amplitudes and coherence. For the coastal portions of t...
