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

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 ...

Isochronous information in a Greenland ice sheet radio echo sounding data set [PDF]
Geophysical Research Letters, 2014 AbstractThe evaluation of ice sheet models is one of the pressing problems in the study of ice sheet dynamics. Here we examine the question of how much isochronous information is contained within the publicly available Center for Remote Sensing of Ice Sheets (CReSIS) Greenland airborne radio echo soundings data set.
