Joint Effects of Clouds and Rain on EHF Satellite Communication Systems

This contribution addresses the evaluation of the simultaneous impact of clouds and rain on electromagnetic waves in the EHF band. To this aim, MultiEXCELL and SMOC, two physically-based models recently developed to synthesize realistic rain and cloud fields, are employed. Taking advantage of their physical soundness, the two models are combined to derive, as an example, the simultaneous attenuation due to rain and clouds on a geostationary link operating at 39.6 GHz, as well as the gain that a two-site diversity system would achieve.
