Validation of Glacier Topographic Acquisitions from an Airborne Single-Pass Interferometer
International audience The airborne glacier and ice surface topography interferometer (GLISTIN-A) is a single-pass radar interferometer developed for accurate high-resolution swath mapping of dynamic ice surfaces. We present the first validation results of the operational sensor, collected in 2013 o...
