Swiss alpine airborne sar experiment (SASARE) part II - imaging of high alpine glaciers at the VHF-band

For part I see ibid., (2004). This paper describes first results from a low frequency sensor campaign in the high Alpine region of Switzerland. Several parallel tracks were flown with the Swedish radio wave sensor CARABAS-II in late autumn 2003. We rate the geometric quality of the automatic processing of the ultra-wideband (UWB) radar data, discuss its most characteristic features, as well as problems caused by highly variable topographic gradients. The relatively long wavelengths used should theoretically allow penetration into cold ice bodies. The first results did not show obvious evidence of subsurface echoes
