Abstract

Modelling of wave propagation for modern high-frequency radio links must take into account the fluctuation phenomena caused by random changes of the medium's parameters. There are two factors that cause signals from transmitter to receiver to arrive via multiple random paths. The first is a result of scattering by boundaries and various obstacles, while the second is related to random changes in the refractive index of the medium. Similar phenomena are observed in underwater acoustic propagation. In this work the influence of both factors is demonstrated in a simple example when the propagation takes place above a perfectly reflecting surface in the presence of a randomly fluctuating medium.
