Abstract

L'invention est relative à un modulateur modulaire à largeur d'impulsion variable. Le modulateur comporte un étage séparateur connecté à une source d'alimentation haute tension. La sortie de l'étage séparateur est connectée à un circuit générateur d'impulsions lui-même relié par l'intermédiaire d'un circuit coupleur 4 au tube d'émission 5. Ce circuit générateur d'impulsions comporte une pluralité de cellules à retard élémentaire 61... 6n connectée chacune au circuit de couplage 4 par l'intermédiaire d'au moins un circuit de commutation 71, 72... 7n et l'électrode de déclenchement des circuits de commutation à un circuit de commande 8 délivrant en séquence des signaux de déclenchement à des instants différents déterminés. Application aux émetteurs radar à durée d'émission variable.
