Scintillation Characteristics from Experiment on 11 GHz Terrestrial Path

摘要

Scintillation of electromagnetic waves is studied by the statistical analysis of received power fluctuations measured on the terrestrial microwave path operating in 11 GHz band. The obtained cumulative distributions of standard deviation of attenuation are shown to follow a log-normal distribution model. Structure constant of refractive index of air is derived by two methods - from the radio signal fluctuations and from the vertical profiles of meteorological data. A good agreement is achieved between annual statistics of structure constants derived by both methods.
