Abstract

L'invention concerne un système de corrélation d'événement périodique, selon un critère de corrélation de p parmi q. Le système comporte une boucle de traitement se refermant sur un additionneur analogique 1 d'entrée, dont le signal analogique de sortie B est dirigé sur un détecteur de seuil 2 pour fournir, en sortie, un signal logique S, résultat de la corrélation. La boucle de traitement comporte, en série avec l'additionneur 1, un circuit écrêteur 3, un dispositif de retard 4, un amplificateur 5 et un comparateur 6. L'invention s'applique aux radars secondaires.
