Extension of a predictive model for the differential rain attenuation on adjacent Earth-space propagation paths

One of the main propagation effects on interference between adjacent Earth-space paths is considered to be the differential rain attenuation. An existing method for the prediction of the above statistical variable is properly modified by taking into account more realistic considerations for the rain height. The results of the modified method are compared with available simulation data in Montreal area. The influence of the novel assumptions for the rain height on the differential attenuation, as function of the various parameters of the problem, is also examined. >
