Abstract

Abstract

The density-depth relationship of the Antarctic ice sheet is one of the key parameter when building the high-precision surface mass balance model. An ice sheet density and permittivity inversion method is proposed based on Frequency Modulated Continuous Wave (FMCW) radar. The density profile is preliminarily inverted firstly by the layer stripping inversion method. Then the density model is established by the shallow inversion density and the ice sheet densification empirical equation. Finally, the optimal model parameters are found through the optimization algorithm to calibration the density. Experimental results based on theoretical ice sheet models and measured radar data verify the effectiveness of the new method.
