A New Prediction Model of Rain Attenuation That Separately Accounts for Stratiform and Convective Rain

IEEE Transactions on Antennas and Propagation, 2009
An improved version of the exponential cell (EXCELL) rain attenuation model is presented here. Analogously to the original one, it predicts attenuation through a cellular representation of precipitation, but, in addition, is able to discriminate between stratiform and convective rain by means of an embedded algorithm. Accordingly, two separate physical

Statistical Behavior of Rain Attenuation*

Bell System Technical Journal, 1973
Thirty-one sets of experimental data on the statistics of microwave rain attenuation at frequencies above 10 GHz, in the U.S.A., England, Japan, Italy, and Canada, indicate that: (i) the distribution of rain attenuation α, in dB, is approximately lognormal with a standard deviation σ α of log 10 α ranging from 0.46 to 0.71 for earth-space paths, and ...

Modeling of rain and slant path rain attenuation

2008
The adverse impact of rain on the earth-satellite communications in the region has not been well characterized due to the lack of measured data. In view of the rapid introduction of new business and personal communications networks, based on satellite constellation operation in Ku-band or higher band with low fade-margins, it is of pressing importance ...

Rain Attenuation Prediction Methods

1986
The evaluation of the effects of rain on a satellite system design requires a detailed knowledge of the attenuation statistics for each ground terminal location at the specific frequency of interest. Direct long-term measurements of rain attenuation for all of the ground terminal locations in an operational network are not practical, therefore modeling

Rain attenuation at 74 Ghz

2010
A millimetric wave transmission link of the radar type has been established at the University of British Columbia campus. It operates at 74 GHz and has a 1.8 km total transmission length. The RF source is an unmodulated klystron and a phase-locked receiver is used to detect the received signal.
