Abstract

Calculations on transmission effects through rain are presented. Based on a special form of the radiative transfer equation treated in [1], numerical values are given for coherent propagation through a medium composed of a set of uncanted spheroidal drops, oscillating raindrops and bistatic radar scattering crosssections of rain of uncanted spheroidal drops. Calculations have been made for the range 10–100 GHz. Examples are chosen forOtsfrequency bands (11.5 and 14 GHz) and Louvainla-Neuve experimental link (12 GHz).

Analyse

Des résultats de calculs de transmission à travers la pluie sont présentés. Les valeurs numériques déduites d’une forme particulière de l’équation de transfert radiatif traitée dans [1] ont été calculées pour trois modèles théoriques : propagation cohérente à travers un milieu comprenant une distribution de gouttes sphéroïdales non inclinées, même modèle pour des gouttes oscillantes, aires effectives de diffusion bistatique pour une distribution de gouttes sphéroïdales non inclinées. Les calculs ont été effectués pour la bande 10–100 GHz. Les résultats obtenus aux fréquences du satelliteOts(11,5 et 14 GHz) et des expériences effectuées à Louvain-la-Neuve (12 GHz) sont présentés.
