| Summary: | Satellite to earth links operating at Ku, Ka, and V
bands are strongly attenuated by rain. Rain attenuation is the
most significant parameter which degrades the performance of
the links. Hence, it is essential for satellite link designer to take
into account rain fade prediction accurately before system
implementation. Rain rate is the main parameter to predict of
rain attenuation. Rainfall statistical data measured and
recorded in Libya with 3-hours integration time for the period
of 30 years are collected. The prediction methods require one
minute integration time rain intensity. Hence, collected data
were analyzed and processed to convert into one –minute rain
rate cumulative distribution in Libya. Several prediction models
have been utilized for conversion with consideration of the
climatic condition of the study case area. One prediction model
was recommended to predict one-minute rain rate distribution
for microwave link design in Libyan environment. The
converted rain rate data are used to predict the variation in rain
fades characteristics at C,Ku,Ka and ,V-bands in different parts
of the country using The International Telecommunication
Union Radio wave Propagation models (ITU-RP). Results show
agreement with the model by Chieko and Yoshio . |
