Comparison of COSMO-SkyMed and RADARSAT-2 offset tracking results on David-Drygalski glacier (Antarctica) surface velocities
This note is about the comparison of coregistration offset tracking velocities of a glacier obtained with SAR sensors characterized by different wavelengths and spatial resolutions: Cosmo-SkyMED (X band) and RADARSAT-2 (C band). The study area is represented by the initial part of the David Glacier,...
