HYDROMETEOR ATTENUATION DISTRIBUTIONS AT 58 GHz AND 93 GHzOBTAINED ON AN 850 m PATH

摘要

Cumulative distributions of attenuation due tohydrometeors (rain, rain with snow, snow, fog) obtainedat 58 GHz and 93 GHz on the same terrestrial path withthe length of about 850 m are presented. Results wereobtained over a 9-month period and were recalculated to awhole year period. The obtained cumulative distributionsof attenuation due to all hydrometeors together as well asdue to individual hydrometeors are shown. Availabilityperformances of both the used microwave systems at58 GHz and 93 GHz are assessed. Cumulativedistributions of attenuation due to rain at both frequenciesare compared with the relevant ITU-R recommendations.
