Swiss alpine airborne sar experiment (SASARE) part I: multi-baseline polarimetric SAR inter-ferometry studies at L- and P-band

In the frame of the Swiss Alpine Airborne SAR Experiment 2003 (SASARE) multitemporal/-baseline Pol-InSAR (polarimetric SAR interferometry) data sets were acquired with the German E-SAR (Experimental SAR) platform at L- (1.3 GHz) and P-band (350 MHz) in the region of the Great Aletsch glacier in Switzerland. For SASARE, several sub test sites had been selected below and significantly above the equilibrium line. One of the two campaigns was designed as a joint venture experiment and therefore also includes measurements of the Swedish CARABAS UWB (Coherent All Radio Band Sensing, ultra wide-band) sensor operating in the VHF frequency range (20-90 MHz). 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
