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 کاملDetermination of Geospatial Changes of the Barnes Ice Cap Using Eo Data
The determination of spatial changes in the arctic regions contributes to the understanding and quantification of spatio-temporal phenomena occurring in the polar environments and ecosystems. This paper presents the applicability of air and spaceborne earth observation data in the estimation of planimetric and elevation changes of the Barnes ice cap, located on Baffin Island, Nunavut in Norther...
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 کاملAtmosphere sounding using GPS radio occultation
Introduction On July 17, 1995 the U.S. Air Force announced “ .. that today the Global Positioning System (GPS) satellite constellation has met all requirements for Full Operational Capability”. Apart from precise positioning GPS signals also can be used to derive characteristic properties of the propagation medium (neutral atmosphere and ionosphere). Onboard the Low-Earth-Orbiting MICROLAB-1 sa...
متن کاملPhase Noise Effects on Wideband Mobile Radio Channel Sounding
Abstract – In this work three wideband mobile radio channel sounding methods are simulated and compared using computational tools. The considered sounders include the traditional STDCC and two other proposed sounding methods that are based on OFDM digital transmission and detection procedures and on matched filtering. The impact of the phase noise introduced by the receiver local oscillator in ...
