Glacier radar sounding using multiple-frequency bands

摘要

Abstract: A glacier consists of physical structures covering a large span of length scales. The different scales can be mapped using different radar frequencies. The bottom topography is mapped using HF frequencies (5 - 20 MHz). The internal structure is seen at UHF frequencies (100 - 500 MHz). The snow cover and firn layers can be mapped with frequencies around 1 GHz. !13
