Abstract

La présente invention concerne un système de protection de zones sensibles constitué de bases de détection disposées de façon à ce que chaque base effectue la surveillance d'une partie de la limite de la zone protégée. A chaque base n est alloué un canal fréquentiel de largeur B' centré sur une fréquence Fn. Chaque base comporte une pluralité de radars UHF émettant des impulsions de largeur spectrale B, avec une fréquence de répétition Fr élevée. Chaque radar traite une fraction bo de la bande Doppler globale b1 considéré. Les fréquences d'émission des différents radars constituant une même base sont définies de façon à ce que l'écart entre la fréquence d'émission Fi d'un radar de la base et la fréquence Fn soit inférieur à la fréquence de répétition Fr et que l'écart entre les fréquences d'émission Fi et Fj de deux radars d'une même base soit supérieur à (b1 + b0)/2. Le canal alloué à une base n ainsi que les fréquences d'émission allouées aux radars de cette base sont définis de façon à ce que, compte tenu de la position de la base, aucun des radars constituant la base considérée ne soit susceptible d'être perturbé d'un point de vue radioélectrique par les radars des autres bases.
