Time-series of attenuation on EHF and SHF fixed satellite links derived from meteorological and forecast data

A method for deriving time-series of attenuation on fixed satellite or terrestrial links is described. The method uses meteorological forecast data and radar data and hence permits time coincident derivations for multiple sites that include the spatial correlation properties inherent in weather systems. The success of the technique depends upon insertion of the short interval temporal properties (varying typically over 1 second to 15 minutes) that are statistically independent between stations. The technique has immediate application to simulation of the performance of multimedia satellite to earth links and has longer-term significance in terms of operational real-time performance prediction.
