Imaging of snow/ice subsurface features from airborne SAR at UHF, L and X band. The ONERA SAR campaign in South Greenland
International audience An acquisition campaign of the ONERA airborne synthetic aperture radar system RAMSES have been set up on the Greenland ice-shelf to assess the detectability of buried objects and subsurface feature through dry snow/ice cover. Three band were investigated UHF band, L band and X...
