Radiowave amplitude scintillation intensity: Olympus satellite measurements and empirical model

摘要

The authors summarise the results of a 1 year measurement of earth-space radiowave amplitude scintillation using the Olympus satellite 20 GHz beacon signal received at Sparsholt (51.585/spl deg/N. 1.5033/spl deg/W), UK at a path elevation of 28.74/spl deg/. The diurnal and seasonal trends of scintillation intensity are discussed. A generalised semi-empirical model is obtained, which gives excellent fit to the observed cumulative distribution of scintillation intensity.
