Abstract
L'invention propose une antenne (1) comprenant : une première (2) et une deuxième (3) sous-antennes linéaires munies de capteurs (21-2M, 31-3N) forma nt des première et deuxième portions de lignes et générant un signal de base (Si', Gj'), l'angle entre des vecteurs directeurs respectifs des première et deuxième tangentes au milieu respectivement des première et deuxième portion s de ligne étant compris entre 30~ et 150~ ; un dispositif de traitement d'antenne (4, 5) formant des signaux combinés (VSi, VGj) ; un dispositif de traitement (6, 7) de signal générant des signaux combinés utiles (TSi, TGj) ; un dispositif de calcul (8) des coefficients de corrélation ([Cij]) entre le s signaux combinés utiles ; un dispositif (8) générant un signal de détection ([Rij]) lorsqu'un coefficient de corrélation dépasse un seuil. L'invention permet notamment d'obtenir une antenne présentant un nombre de capteurs inférieur pour un niveau de performances équivalent.
