Abstract

L'invention concerne les ensembles de balayage et de direction de faisceau d'énergie. Elle se rapporte à un ensemble de balayage et de direction qui comprend plusieurs groupements d'éléments émetteurs, chaque groupement étant relié à un circuit réglable de distribution de signaux d'arrangement qui comprend lui-même plusieurs circuits déphaseurs et/ou de retard ou de séquence pondérés convenablement, les faisceaux directionnels étant créés et balayés par commande du circuit formateur de faisceau d'arrangement qui comprend les circuits déphaseurs, à retard ou de séquence, le circuit formateur de faisceau de groupe, faisant partie de l'ensemble de direction de faisceau, étant commandé simultanément afin que les facteurs de groupe et le facteur d'arrangement soient modifiés afin que la configuration résultante du faisceau ne comprennent pratiquement pas de lobes parasites de réseau. Application à la commande du balayage du faisceau d'un rideau d'antenne.
