Cet article décrit l'élaboration d'un modèle unidimensionnel d'une chambre réverbérante permettant la prédiction analytique du comportement statistique d'une telle chambre, sans renoncer aux bénéfices des modèles déterministes. Les propriétés statistiques sont introduites en faisant varier la taille d'un brasseur unidimensionnel ou bien celle de la cavité elle-même. Ce modèle conduit à des résultats conformes à la théorie et aux mesures effectuées en chambres réelles. Les statistiques des champs en régime sous-modal sont étudiées. Une procédure de teste de la radiation émise est définie et les résultats obtenus sont conformes à la réalité. La performance près des parois conductrices est étudiée.

This work focuses on building a fairly simple yet physically appropriate 1D model for a Reverberation Chamber which claims to be able to analytically predict the statistical behavior of such a chamber, without forsaking to the benefits of deterministic models. The statistical properties are introduced by varying the size of a 1D stirrer or the cavity size itself. A validation analysis shows agreement with other theories and measured results on real RCs. Field statistics in undermoded regime is examined. A radiated emission test is defined and shows reliable matching with reality. The field performance near the conducting walls is investigated.
