Abstract
L’invention concerne un formateur analogique multifaisceaux de plusieurs faisceaux radiofréquences bidimensionnels de tailles et/ou directions de pointage variables continument pour une antenne réseau active bidimensionnelle reconfigurable, comprend un premier ensemble (112) de formateurs analogiques multifaisceaux de faisceaux fixes unidimensionnels, de structure identique, superposés et connectés en sortie à des rangées de sources rayonnantes élémentaires d’un réseau antennaire (104) plan suivant une première direction axiale X. Le formateur analogique multifaisceaux comporte un deuxième ensemble (114) de deuxièmes formateurs analogiques unidimensionnels de faisceaux radiofréquences, continument variables en taille et/ou en direction de pointage suivant des deuxièmes directions angulaires de pointage By le long d’une deuxième direction axiale Y. Chaque deuxième formateur analogique est formé par un diviseur à entrée unique et R branches de sortie en mode émission, chaque branche de sortie du diviseur incluant un point de contrôle en amplitude et en phase. Chaque deuxième formateur analogique du deuxième ensemble est connecté à au moins une colonne d’accès du premier ensemble de premiers formateurs analogiques, une colonne d’accès étant formées de R bornes d’accès aux voies d’entrées de même rang j des premiers formateurs analogiques.
