Abstract
L'invention concerne un radar de marine avec un dispositif de visualisation à luminosité constante. Les fréquences de commutation des sources d'alimentation sont indépendantes les unes des autres ainsi que des fréquences d'horloge de données et de repétition d'impulsions, les fréquences de commutation des sources d'alimentation étant intermédiaires entre les fréquences d'horloge et de répétition d'impulsions. Des dispositions sont prises pour commuter la largeur de bande en fonction du réglage de portée. Un circuit de commande de sensibilité ainsi qu un dispositif de stabilisation du nord sont également prévus. L'invention s'applique notamment à un radar indicateur de gisement
