First result from 15.3-GHz earth-space propagation study

Consideration is being given to the use of frequencies well above 10 GHz for satellite communication. One of the problems encountered in the use of these high frequencies is the attenuation caused by precipitation. A considerable amount of pertinent data has been obtained in the 16- and 30-GHz sun tracker and 16-GHz radiometer programs underway at the Crawford Hill Laboratory.1,2 From the data obtained from radiometer measurements, one may calculate the attenuation expected on an earth-space path. Such attenuation calculations have been shown to be in good agreement with sun tracker measurements.1 The present experiment was designed to check further the validity of the radiometer results by a direct comparison of the data obtained from a 16-GHz radiometer with the attenuation measured by transmission from a the afternoon of April 24, 1970. The peak measured 15.3-GHz signal attenuation and the corresponding 16-GHz radiometer record were 9.8 dB and 10.6 dB respectively.)
