Abstract

L'invention concerne l'identification automatique d'objets. Le dispositif de l'invention comprend un circuit d'interrogation 13 qui attaque une antenne d'émission/réception 15 par l'intermédiaire d'un duplexeur 14. Un dispositif répondeur 4, en couplage électromagnétique avec l'antenne 15, comprend un certain nombre de résonateurs 71 , 72 , ...7n qui fournissent une réponse de résonance caractéristique, lorsque le circuit d'interrogation 13 émet un signal à balayage de fréquence. Application à l'identification automatique de wagons.
