A model for the prediction of the differential rain attenuation between a terrestrial line-of sight radio relay system and a low angle satellite path based on the two-dimensional gamma distribution

The main propagation effect on interference of a terrestrial line-of-sight radio relay system from a low-angle satellite path is the differential rain attenuation. In the present paper, a predictive method for the differential rain attenuation statistics is proposed which is based on the assumption that the point rainfall statistics follows a gamma form. The results of the predictive procedure are applied to a particular problem of terrestrial line-of-sight system interference from a low-angle broadcasting satellite service in the 22 5-23 GHZ band. Some useful conclusions are deduced.
