Abstract
RADAR PERMETTANT UNE DETECTION PROCHE DU TYPE EXIGEE POUR UNE FUSEE DE PROXIMITE DANS DES CONDITIONS D'EVOLUTION A TRES BASSE ALTITUDE. IL COMPORTE DEUX VOIES DE CORRELATION COUVRANT UNE PLAGE COMMUNE DE MESURE POUR FONCTIONNER EN ALTIMETRE PAR PRODUCTION D'UN SIGNAL DIFFERENCE S4 CONTROLANT EN FREQUENCE UN OSCILLATEUR LOCAL 13. L'INFORMATION FREQUENCE LOCALE EST UTILISEE POUR ASSERVIR LA POSITION EN ALTITUDE S6, S8. UNE TROISIEME VOIE EST UTILISEE POUR LA DETECTION PROCHE ET LE DECLENCHEMENT D'UNE MISE A FEU 12. L'INVENTION S'APPLIQUE NOTAMMENT AUX MISSILES D'INTERCEPTION A BASSE ALTITUDE.
