Anisotropic scattering in radio-echo sounding: insights from northeast Greenland [PDF]

open access: yesThe Cryosphere
Anisotropic scattering and birefringence-induced power extinction are two distinct mechanisms affecting the azimuthal power response in radio-echo sounding (RES) of ice sheets.

Radio echo sounding in the Shirase Glacier drainage basin

open access: yesAntarctic 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 ...

Editorial for the Special Issue “Review of Application Areas of GPR”

open access: yesRemote Sensing, 2023
Ground-penetrating radar (GPR) started as a radio echo sounding technology during the second half of the last century, but it is now a well-established and widely adopted technology for producing high-resolution images of subsurface [...]

Radio-frequency probes of Antarctic ice at South Pole [PDF]

open access: yesThe Cryosphere, 2013
Using hardware developed for the ARA (Askaryan Radio Array) particle astrophysics experiment, we herein report on the amplitude and temporal characteristics of polarized surface radar echo data collected in South Polar ice using radio sounding equipment ...

Progress in Radio-Echo Sounding Theory [PDF]

open access: yesJournal of Glaciology, 1975
AbstractThe 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 glacier) exists, and ...

Radio-Echo Sounding of Mountain Glaciers [PDF]

open access: yesJournal of Glaciology, 1975
AbstractExperiments 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.

Radio Echo-Sounding of Svalbard Glaciers [PDF]

open access: yesJournal 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.

Simulating the Profile of a Radio Altimeter Echo Signal

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2022
Introduction. Radio altimeters are used for remote monitoring of the Earth and sea surface based on the signal power profile, i.e. the dependence of echo signal power vs time, averaged over a set of sounding measurements. Calculation of the power profile

Multiangle, Frequency, and Polarization Radar Measurement of Ice Sheets

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Radio echo sounding of polar ice sheets provides important information on the ice bed topography and internal layers. These data have been used by scientists to create 3-D maps of polar ice sheets for climate modeling as well as to reconstruct the ...
