Abstract

L'invention concerne les radars continus à modulation de fréquence triangulaire. Selon l'invention, le radar comporte un circuit 10 d'élaboration d'un signal complexe de fréquence variable et constituant la réplique du signal reçu. Le circuit 10 comporte un générateur 11 de signal d'analyse, un circuit de mise en forme 12 et des circuits 13 et 14 réalisant une pondération du signal réplique avant de l'appliquer au corrélateur 8. L'invention s'applique aux radars continus à modulation de fréquence.
