Abstract

L’invention propose une méthode de détection et localisation de cibles situées au voisinage d’un récepteur, qui exploite simultanément plusieurs sources de signaux d’opportunité non colocalisées, par exemple des satellites d’une constellation GNSS. Les signaux émis par des satellites peuvent être réfléchis ou diffractés sur des objets (mobiles ou non) avant d’être interceptés par un récepteur. Compte tenu de la distance importante entre un satellite et l’objet à détecter, les pertes de propagation (ionosphérique et troposphérique) impactant le signal directement reçu par un récepteur et le signal réfléchi sur la cible sont communes. Seule la perte de propagation liée à la réflexion du signal sur la cible et à la propagation du signal réfléchi entre la cible et le récepteur sont à prendre en compte. Figure 3
