RESEARCH ON RADIO-ECHO SOUNDING DATA PROCESSING: A CASE STUDY AT DOME A, EAST ANTARCTICA

doi:10.3724/SP.J.1084.2013.00197

Abstract

Abstract: A method of radio-echo sounding data processing is proposed, and several key techniques, such as static correction, gain control, band-pass filter and migration process, are described in detail. The radio-echo sounding data of a 900 km² area in Dome A, Antarctica obtained by CHINARE 24 is used as an example. We show that the depth of the isochronous layers and the ice thickness of the bedrock can be extracted from the data. Furthermore, a three-dimensional model of the isochronous layers and the bedrock is generated using a suitable interpolation method. Finally, an entire 3D model, including the isochronous layers and the bedrock at Dome A is constructed by combining radio-echo sounding data with ICESat data.

Key words: Radio-echo Sounding, Dome A, Data processing, Isochronous layer, 3D Modeling
