Abstract

Results of an investigation of propagation in snow at 96, 140, and 225 GHz are reported. Measurements were made with the Harry Diamond Laboratories near-millimeter wave mobile measurement facility in snow with mass concentrations up to 0.9 gm/m³. For each frequency a correlation was found to exist between attenuation coefficients and snow mass concentration. Snow backscatter cross sections per unit volume at 96 GHz were found to range between 1 and 7 x 10^-5 m⁴/m³ for snow concentrations between 0.1 and 0.6 gm/m³.
