Abstract
L'invention concerne un système de guidage (1) d'un aéronef (A) comprenant : - une première antenne (10) présentant un premier angle d'ouverture (O1) à - 3 dB, - une deuxième antenne (20) présentant un deuxième angle d'ouverture (O2) à - 3 dB, le premier angle d'ouverture (01) étant au moins deux fois plus grand que le deuxième angle d'ouverture (02) et, au sein du deuxième angle d'ouverture (O2) de la deuxième antenne (20), une valeur absolue d'un écart entre la puissance d'un signal reçu de la première antenne (10) et la puissance d'un signal reçu de la deuxième antenne (20) étant au moins égale à 10 dB.
