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,...
A VHF-band radar is being developed to characterize polar ice sheets and their basal conditions from a UAV developed specifically for low-altitude polar operation. The radar's 195-MHz center frequency, 30-MHz bandwidth, and 200-W transmit power will map internal layers and ice thickness with a depth resolution of less than 3 m in ice, and image the ice-bed interface. To satisfy the mass and volume...
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...
