MILLIMETER WAVE ATTENUATION THROUGH SNOW,
Abstract
Measurements of the attenuation of electromagnetic radiation through snow and the reflection of radiation from snow were made by using an interferometer and manufactured snow in an environmental chamber under closely controlled conditions. The ambient temperature was varied from -4 to +32 F, and the signal frequency from 31 to 38 Gc. No surface icing of the snow was allowed to form during the measurements. The signal losses for 10 different frequencies at two snow-sample temperatures are tabulated. Curves of the variation in attenuation and reflection as a function of temperature show that below 23 F the amount of energy reflected and the amount lost in attenuation decrease slowly with decreasing temperature.
