Abstract
Système radar équipé de deux générateurs d'impulsions destinés à générer respectivement des impulsions modulées en fréquence de durée relativement longue et des impulsions de duree relativement courte, ainsi que d'un canal d'émission connecté aux générateurs et par lequel sont émises des impulsions des deux types, le systeme radar étant en outre équipé d'un récepteur avec un premier canal de réception pour la détection de signaux d'écho issus des impulsions modulées en fréquence de durée relativement longue et un deuxième canal de réception pour la détection de signaux d'écho issus des impulsions de durée relativement courte. La fréquence de récurrence du second générateur d'impulsions est supérieure à celle du premier. L'invention est applicable à des radars fonctionnant avec deux types d'impulsions.
