Time-series of Attenuation on Ehf and Shf Fixed Radio Links Derivedfrom Meteorological Forecast and Radar Data

A method for deriving attenuation time-series on fixed satellite or terrestrial links is described. The method uses meteorological forecast and radar data and permits time coincident derivations for multiple sites that include the inherent spatial correlation properties. The paper describes the approach adopted in the technique and presents preliminary results for two sites in the UK. The time-series and spectra generated by the simulator show promising similarity with those measured on an Earth-space link for the same period. The technique has application in performance simulation for satellite to earth links and has longer-term significance in terms of real-time operational use.
