“…The atmospheric refractivity models used with ray tracing are usually very simple and only give a rough approximation of the propagation channel behavior. These models generally assume one (or two) stable superrefractive layer superimposed on a standard atmospheric refractivity profile [Webster, 1982;Parl, 1983;Kheirallah et al, 1987;Marnhoud et al, 1987]. Even if these models do not allow one to explain all the observed radioelectrical phenomena [Claverie and Klapisz, 1985], it may be expected that they describe the basic features of the propagation channel.…”

A ray tracing approach with a statistical model of the atmospheric refractivity is used to get angle-of-arrival, amplitude and delay time distributions in a multipath situation. The atmospheric model considers a single superrefractive layer. Statistics of the layer parameters (height, intensity, and thickness) are derived from meteorological data. Ray tracing calculations include rays reflected from a flat ground. The influence of the various layer parameters as well as the physical origin of the rays are analyzed and discussed. Some experimental evidence relating to, and confirming, the predicted values is also considered.
