Abstract

In this paper a new model oriented approach to measuring rain-induced cross-polarization is outlined: it aims at characterising the physical properties of the depolarising medium rather than at directly measuring the channel depolarization, which is the variable of direct interest for system design. This approach, which allows subsequent determination of depolarization has the advantages of allowing a better understanding of the propagation mechanism, thus yielding information applicable to any system configuration and establishing common procedure to compare cross-polarization data obtained in different circumstances. Different experimental configurations are reviewed together with their ability to identify and assess various possible models for the depolarizing medium.

Analyse

Cet article présente une nouvelle méthode de mesure, à partir de modèles, de la transpolarisation due à la pluie destinée à caractériser les propriétés physiques du milieu dépolarisant plutôt qu’à mesurer directement la dépolarisation de la voie de transmission. Cette méthode est surtout intéressante au niveau de la conception. Elle permet le calcul ultérieur de la dépolarisation et conduit à une meilleure compréhension du mécanisme de propagation. Les résultats sont applicables à des systèmes de configuration quelconque et permettent d’établir des procédures générales de comparaison des données. Différentes configurations expérimentales sont examinées du point de vue de leur modélisation éventuelle.
