Abstract

Procédé de localisation tridimensionnelle comportant au moins quatre transducteurs disposés selon deux plans de référence et un projecteur ou répondeur porté par le plongeur. Selon une forme simple, des hydrophones 1 sont disposés au sommet d'un volume géométrique entourant une structure. Le plongeur P est muni d'un répondeur qui est interrogé par un projecteur 2 disposé près d'un hydrophone 1. Les temps sont envoyés à un calculateur qui en fonction des distances des hydrophones et projecteurs détermine, en fonction des caractéristiques du milieu, les coordonnées du plongeur et les enregistre. Application aux contrôles des structures immergées.
