Radio echo sounding in the Shirase Glacier drainage basin
Antarctic Record, 1986 Airborne radio echo sounding was carried out in order to measure the thickness of the ice sheet in the Shirase Glacier drainage basin. From the analysis of the result obtained, the bedrock topography was estimated and it was found that the elevation of ...

Progress in Radio-Echo Sounding Theory [PDF]
Journal of Glaciology, 1975 Abstract The inverse problem of radio-echo sounding consists in the reconstruction of subglacial relief from the known radio-echo profile, and the path, and speed of the aircraft. The present work shows that in the geometrical optical approach the solution of the inverse problem for a homogeneous, two-dimensional object (valley ...

Radio Echo-Sounding of Svalbard Glaciers [PDF]
Journal of Glaciology, 1982 AbstractPeculiarities of radio echo-sounding of mountain glaciers and ice fields between nunataks from terrestrial vehicles and from helicopters are considered in this paper. The possibility of using comparatively high frequencies (of up to 865 MHz) for sounding such glaciers is demonstrated on the basis of experimental data.

Radio Echo Sounding: Brine Percolation Layer [PDF]
Journal of Glaciology, 1973 Abstract An abrupt change in radio echo sounding travel time was observed on the ice shelf near McMurdo station, Antarctica, and was mapped by a zig-zag traverse. This boundary corresponds to the horizontal extent of brine penetration into the edge of the ice shelf.

Radio-Echo Sounding of Mountain Glaciers [PDF]
Journal of Glaciology, 1975 Abstract Experiments on radio-echo sounding of mountain glaciers have been done on Lednik Marukh (west Caucasus), Lednik Bezingy and Lednik Dzhankuat (central Caucasus), Lednik Gergety (east Caucasus), and Lednik IGAN (Polar Urals) in 1967-71 as a part of the I.H.D. programme.

Coherent large beamwidth processing of radio-echo sounding data [PDF]
The Cryosphere, 2018 Coherent processing of radio-echo sounding data of polar ice sheets is known to provide an indication of bedrock properties and detection of internal layers.

Radio echo sounding data analysis of the Shackleton Ice Shelf
Annals of Geophysics, 2010 In this study, our initial results are presented for the interpretation of the radio echo sounding data collected over the Shackleton Ice Shelf and adjacent ice sheet (East Antarctica) during the 2003/2004 Australian-Italian expedition.

Radio Echo Sounding on a Valley Glacier in East Greenland [PDF]
Journal of Glaciology, 1973 Abstract Although radio echo sounding equipment has been used with success for measuring the thickness of ice sheets in the Arctic and Antarctic, a valley glacier poses the additional problems of echoes from the valley walls, which may obscure the bottom echoes, and a high attenuation of radio waves in the ice.

Radio Echo Sounding of Horizontal Layers in Ice [PDF]
Journal of Glaciology, 1973 Radio echo-sounding surveys of Antarctica and Greenland have revealed extensive layering within the ice. Formulae for the effective reflection coefficient, when viewed by a pulsed radar, are derived for isolated or multiple randomly spaced layers.
