Statistics of Attenuation by Rain of 13 Ghz Signals on Earth-Space Paths in Canada

摘要

To accomodate the increased number of users of radio signals, communication systems are being designed more and more to operate at microwave frequencies that were hitherto unused. A major difficulty with frequencies above 10 GHz is that they are attenuated by rain. Attenuation statistics and fade rate statistics from six locations, all in Canada, are presented for 13 GHz signals on Earth-space paths. These statistics are based on a total of 15.7 station-years of attenuation measurements with the operating time of the individual stations ranging from 1.68 to 4.91 years.
