We developed and deployed, in July 2005, a wideband 8-channel synthetic aperture radar (SAR) at Summit Camp, Greenland (72.5783° N and 38.4596° W). The radar was designed to map internal layers, measure topography, and generate backscatter maps - all in a single pass. Information on ice thickness, bed topography and basal conditions is essential to the refinement of glaciological models of ice sheets,...
An 8-channel ground-based radar has been developed and used to image the ice-bed interface under the icesheet near Summit Camp, Greenland. This radar, which chirps from 120 to 300 MHz, was developed to demonstrate the feasibility of using radar to characterize the basal conditions (topography, roughness, and presence of liquid water) thus enabling improved modeling of ice-sheet dynamics. Using a basal...
Ice sheet models are necessary to understand ice sheet dynamics and to predict their behavior. Of the primary inputs to these models, basal conditions are the least understood. By observing the forward and backscatter across a wide frequency range (over two octaves) the basal conditions can be established with a high level of confidence. For this purpose, we developed a multistatic synthetic aperture...
