Abstract

Microwave transmission loss in a natural snowpack was measured to provide fundamental data for snow subsurface radar. The snowpack consisted of many horizontal stratified layers of relatively large density and water inclusion. Field strength measurements were carried out in the vertical direction across horizontal snow layers in the frequency range 0.6-7.0 GHz. The transmission loss and the extinction coefficients were obtained as a function of frequency
