Abstract

Frequency scaling makes it possible to derive rain induced attenuation statistics at higher frequencies on the basis of the available data obtained at lower frequencies. Attenuation data are simultaneously obtained at 11,18 and 30 GHz on the same terrestrial 10 km path. Experimental results are compared with those obtained by various prediction methods and, in many cases, the concordance is quite satisfactory.

Analyse

Cette technique permet de déduire les statistiques d’affaiblissements dûs à la pluie, à des fréquences élevées, à partir des valeurs disponibles à des fréquences basses. Ces affaiblissements sont obtenus simultanément à 11,18 et 30 GHz sur le même trajet terrestre de 10 km. Les résultats expérimentaux sont comparés à ceux obtenus par différentes méthodes de prévision et concordent avec eux dans de nombreux cas.
