Abstract
L'invention concerne un dispositif d'antenne pour la goniométrie, notamment pour le reperage au radar. Ce dispositif est constitué par un réflecteur parabolique 1, formé de deux moitiés symétriques 2, 3, et par deux excitateurs 5 séparés par une paroi intermédiaire centrale 7 qui ne s'étend pas d'un bord à l'autre du réflecteur, mais seulement dans la région des excitateurs 5, une bande métallique 8 remplissant l'espace compris entre les moitiés 2, 3 du réflecteur 1. Application au repérage de cibles par radar monopulsé.
