A comprehensive meteorologically oriented methodology for the prediction of wave propagation parameters in telecommunication applications beyond 10 GHz

摘要

This paper presents a new approach For the prediction of propagation parameters (such as rain attenuation, site diversity gain, interference by rain scattering, etc) in telecommunication applications beyond 10 GHz. It consists of a comprehensive theory allowing the full exploitation of the large amount of meteorological data available today. The method is based on a recently devised statistical model of the rain horizontal structure (Capsoni et al., this issue), whose parameters can be determined on the basis of the local statistical distribution of the point rainfall intensity. A test of the ability of this method in predicting attenuation statistics is performed using data collected in Europe with the satellites SIRIO and OTS (COST 205, 1985). The excellent results obtained encourage the application of the model to the statistical prediction of other parameters pertaining to propagation
