Abstract

The theoretical estimation and experimental determination of the amplitude and phase fluctuations of the microwave signal in the three-centimeter wave band propagating through a turbulent atmosphere on unobstructed paths have been performed. Numerical estimates were obtained for the dispersions and also for the correlation radii of amplitude and phase fluctuations of the microwave signal in the coastal region of the town of Sevastopol. A measuring complex was created and experimental investigations of the amplitude and phase fluctuations of the microwave signal were carried out synchronously with meteorological measurements.
