Abstract

L'invention concerne un montage pour déplacer le spectre de signaux d'échos parasites dans un récepteur radar. Dans ce montage qui comporte un dispositif de retardement VE; VE1 VE2, VE3 branché en parallèle avec un ensemble comprenant des déphaseurs PS2, PS1, un circuit MCA déterminant la variation moyenne de la phase de signaux d'échos parasites, un accumulateur AKU pour la sommation de la variation de phase totale et une mémoire CPA, entre une entrée E et une sortie S, il est prévu une boucle de réaction RFS réalisant le réglage continu du déphaseur PS2 et branchée entre ce déphaseur et la sortie de l'accumulateur AKU. Application notamment aux radars de surveillance à impulsions à effet Doppler.
