Swiss alpine airborne sar experiment (SASARE) part II - imaging of high alpine glaciers at the VHF-band
TLDR
We rate the geometric quality of the automatic processing of the ultra-wideband radar data, discuss its most characteristic features, as well as problems caused by highly variable topographic gradients. Expand

Swiss alpine airborne sar experiment (SASARE) part I: multi-baseline polarimetric SAR inter-ferometry studies at L- and P-band
TLDR
We provide first results from analysis of multitemporal/-baseline Pol-InSAR Land P-band measurements of the polarisation-dependent complex interferometric coherence of different glaciological surface types of an Alpine glacier. Expand
