Abstract

La présente invention concerne un radar de cartographie et plus particulièrement un radar de cartographie pour hélicoptère. Le radar comporte un aérien animé d'un mouvement de rotation circulaire, disposé de préférence à l'extrémité libre d'une des pales de l'hélicoptère, des moyens d'émission-réception couplés à l'aérien, des moyens de démodulation des signaux de réception et des moyens de corrélation des signaux démodulés par un signal synthétique obtenu par modulation de phase d'un signal d'amplitude constante selon le mouvement de rotation de l'aérien. Applications à la détection d'objets fixes ou mobiles.
