Results of the Propagation Measurements at 94 Ghz over a 935 M Link on the Ypenburg Airfield

摘要

Extremely high frequency propagation data and meteorological measurements, including rain rate along the propagation path, windspeed and wind direction in the horizontal plane, the atmospheric temperature, pressure and humidity and raindrop size distribution are given for a vertically polarized Cassegrain antenna link. Actually measured raindrop size distribution and spherical raindrops, were used to measure the attenuation caused by rain using Mie's scattering theory for water spheres. It is noted that in fog, the attenuation is small for millimeter waves and high for infrared waves. Data are collected from point visibility meters, ombrometers and rapid response rain gages.
