Radio Echo Sounding of the Greenland Inland Ice
Radio echo sounding has been used for a number of years in the exploration of polar ice such as the inland ice in Greenland and Antarc tica. By means of this technique a number of important glaciological and geophysical parameters may be deter mined. Examples are ice thickness, bedrock topography and structure, stratification patterns which are used for climate and flow patterns studies, and ...
متن کاملAirborne SAR Tomographic Ice Sheet Sounding
A new tomographic ice sounding method is introduced to provide airborne swath measurements of ice sheet thickness and basal scattering properties. Two major challenges have been solved: left-right signal separation; and surface clutter rejection. The new technique was demonstrated using data we collected in 2006 and 2008 from a VHF-band, multiple phase-center radar system flown in Greenland. Fo...
متن کاملAirborne and spaceborne ice sounding of Antarctica, Mars and Europa
Satellite-based radio echo sounding technique is of interest to the Earth science community over Antarctica and Greenland, as well as to the planetary science community for exploring subsurface structures of Mars and Europa. Pioneered by the Mars exploration community using MARSIS radar on board the Mars Express mission, such a technique has demonstrated ice sounding capability down to a few ki...
متن کاملImaging and sounding of ice fields with airborne coherent radars
The recent development of the synthetic aperture imaging radar [Brown and Porcello, 1969; Harger, 1970; Rihaczek, 1969], which generates high-resolution surface imagery from an airborne or spaceborne platform, has generated interest in the scientific community for its use as an all-time all-weather remote sensor to study the earth's solid surface, oceans, and polar regions [Bradic, 1967; Waite ...
متن کاملInstruments and Methods Improved method to determine radio-echo sounding reflector depths from ice-core profiles of permittivity and conductivity
We present a technique that modifies and extends down-hole target methods to provide absolute measures of uncertainty in radar-reflector depth of origin. We use ice-core profiles to model wave propagation and reflection, and then cross-correlate the model results with radio-echo sounding (RES) data to identify the depth of reflector events. Stacked traces recorded with RES near the EPICA drill ...
