Abstract

L'INVENTION CONCERNE UN DISPOSITIF RECEPTEUR REPONDANT A DES RADIATIONS ELECTROMAGNETIQUES TELLES QUE DES IMPULSIONS DE RADAR. LE DISPOSITIF COMPREND UN RESEAU D'ANTENNES ET UN EQUIPEMENT DE TRAITEMENT DE SIGNAUX COOPERANT, CE DISPOSITIF ETANT CAPABLE DE TRAITER DES SIGNAUX PROVENANT DE LA RADIATION ELECTROMAGNETIQUE INTERCEPTEE PAR LE RESEAU D'ANTENNES DE MANIERE A OBTENIR UNE DETERMINATION SANS AMBIGUITE DE LA RELATION DIRECTIONNELLE ENTRE LE RESEAU D'ANTENNES ET LA SOURCE DE LA RADIATION. APPLICATION A LA RECEPTION DES SIGNAUX DE RADAR.THE INVENTION RELATES TO A RECEIVING DEVICE RESPONDING TO ELECTROMAGNETIC RADIATIONS SUCH AS RADAR PULSES. THE DEVICE INCLUDES AN ANTENNA NETWORK AND A COOPERATING SIGNAL PROCESSING EQUIPMENT, THIS DEVICE BEING CAPABLE OF PROCESSING SIGNALS FROM ELECTROMAGNETIC RADIATION INTERCEPTED BY THE ANTENNA NETWORK SO AS TO OBTAIN AN UNAMBIGGED DETERMINATION BETWEEN THE RELATIONSHIP THE ANTENNA NETWORK AND THE SOURCE OF RADIATION. APPLICATION TO THE RECEPTION OF RADAR SIGNALS.
