Description
Summary:During the winter of 1977/78 RADC conducted a measurement program on the backscatter, bistatic scatter, and attenuation properties of metamorphic snow at millimeter wavelengths. After going through an aging process, snow cover on the ground develops sufficient internal strength so that slabs can be cut from it and removed for measurement. Low-power CW equipment was designed and constructed to conduct scatter and attenuation measurements on snow slabs at frequencies of 35, 98, and 140 GHz at vertical, horizontal and crossed polarizations.
