Measurements of satellite-to-ground RF path attenuation at 12 GHz in southern Florida
Abstract
A low cost digital recording is made of satellite slant path RF rain attenuation of the 12/14 GHz SBS-1 in southern Florida over the period of a year. Using a radiometer and a rain gauge, cumulative statistics are compiled of sky noise temperature, rain intensity, fading duration for various fading depths, and average fading lengths as computed in attenuation increments of 1 dB. Good agreement is obtained with the theoretical model. For the example of the 0.1 percentile of the year, an excess rain attenuation of 5.1 dB was measured as compared with the predicted value of 6.0 dB. The observed yearly rain outage of 9.4-9.9 hours is only slightly less than the 25-year Rice/Holmberg statistical average of 11.8 hours.
