A new approach of the problem of electromagnetic wave scattering by a turbulent medium is described. The authors show that, in the troposphere, one can model the refractive index structure constant Cn2 as a random function. The probability density function of the received power, scattered by the medium, is then determined. The method is applied to UHF tropospheric beyond line of sight radio links. Results are compared with those given by a fairly accurate semi empirical model for such links: NBS 101. A good agreement is obtained for large antennas and for frequencies greater than 3 GHz
