Tracing the Layer Boundary of the Ice Sheet from Radio-Echo Sounding Data

Based on a compartmental model and the dielectric properties of the ice sheet, this paper presents a layer boundary tracing method for tracing the boundaries of different dielectrics of the ice sheet. In this paper, the empirical mean curve decomposition (EMCD) method is used to extract the slowly-varying envelope of radio-echo sounding (RES) signal to build a comparmental model of RES data and realize the boundary tracing. Experimental results show that the compartmentalization of ice sheet can be realized and the boundaries of ice sheet can be traced based on the RES data collected during the 29th Chinese Antarctic Research Expedition (CHINARE 29) by the Institute of Electronics, Chinese Academy of Science (IECAS).
