Abstract

L'invention se rapporte à un système de guidage à pseudo-bruit à ondes entretenues. Pour supprimer l'énergie de fuite d'émetteur transmise directement de l'émetteur au récepteur, on prévoit de décoder l'énergie de fuite d'émetteur reçue sur l'antenne 20 à l'aide d'un démodulateur et d'un décodeur auxiliaires 24, 28 en laissant l'énergie réfléchie d'une cible à large bande. Cette énergie de fuite d'émetteur réduite sensiblement à une fréquence unique est fortement atténuée dans un filtre éliminateur de bande 25 qui n'atténue que très peu le signal de cible à large bande. Un modulateur 26 permet de supprimer le codage supplémentaire appliqué aux signaux de cible par le démodulateur 24. L'invention s'applique aux systèmes radar de guidage.
