Abstract

The main propagation effect on interference between adjacent Earth-space paths is differential rain attenuation. In the present paper a method to predict the rain differential attenuation statistics is proposed which is based on a model convective rain cell structure of the rainfall medium. The assumption that the point rainfall statistics follow a lognormal form is also adopted. The results of this method are compared with the available simulation data for the differential attenuation over pairs of paths in the Montreal area. The agreement has been found to be quite encouraging. The sensitivity of various parameters affecting the differential attenuation statistics is also examined.
