Abstract

PRECIS DE LA DIVULGATION:

Antenne à balayage électronique en émission comprenant un réflecteur focalisant l'énergie et un réseau de sources élémentaires, situé dans la zone focale de ce réflecteur, de manière à réaliser la synthèse du champ électromagnétique dans cette zone focale. L'antenne possède une zone de couverture réalisée par plusieurs spots adjacents, qui est couverte partiellement et simultanément par un ou plusieurs faisceaux dont les accès sont indépendants et utilisant pour cela le même nombre m de sources (ou groupes de sources) élémentaires sélectionnées chacune parmi m classes de sources qui ne sont jamais sollicitées simultanément dans un même faisceau, de telle sorte qu'à chaque instant une source élémentaire appartenant à une classe et une seule soit sollicitée, la commutation des sources assurant l'agilité du ou des faisceaux. L'invention trouve une application notamment dans le domaine des télécommunications spatiales. PRECISION OF DISCLOSURE:

Electronic transmission antenna comprising a reflector focusing energy and a network of sources elementary, located in the focal area of this reflector, of way to synthesize the electromagnetic field in this focal area. The antenna has an area of cover produced by several adjacent spots, which is partially and simultaneously covered by one or more bundles whose accesses are independent and using for that the same number m of sources (or groups of sources) selected each from among m classes of sources that are never used simultaneously in a same beam, so that at every moment a source elementary belonging to a class and only one either solicited, switching sources ensuring the agility of the or bundles. The invention finds an application especially in the field of space telecommunications.
