Abstract

L'invention concerne un circuit d'amplification de récepteur radar. Il comporte plusieurs canaux d'amplification de fréquence intermédiaire et de fréquence d'image qui reçoivent des signaux reçus dans des plages dynamiques différentes d'amplitude de manière que la plage dynamique totale du récepteur soit équivalente à la plage dynamique d'un récepteur normal avec une commande automatique de gain. L'invention s'applique notamment à un radar Doppler pulsé.
