Abstract
L'invention concerne un radar à traitement numérique des signaux d'image, avec un circuit de réjection des interférences causées notamment par des radars voisins. Les signaux d'images de chaque balayage sont mémorisés dans une mémoire à accès direct. Une comparaison est faite entre les cellules de distance voisine du signal d'image actuel et du signal d'image du balayage précédent. Le signal de sortie d'image vers le dispositif de visualisation est inhibé si la comparaison indique la présence d'interférences. L'invention s'applique notamment aux radars de marine.
