Abstract
L'INVENTION SE RAPPORTE A UN PROCEDE ET A UN DISPOSITIF DE MESURE AUTOMATIQUE, PAR ULTRA-SONS, D'ANGLES DANS L'EAU. UNE BALISE 1 EMET UN SIGNAL, CAPTE A DES INSTANTS DIFFERENTS, RESPECTIVEMENT PAR DEUX TETES RECEPTRICES 2 ET 3, REPEREES PAR RAPPORT A UN AXE MEDIAN DE REFERENCE XX, L'ANGLE CHERCHE, OU GISEMENT, ETANT CELUI DEFINI PAR CET AXE ET PAR LA DROITE JOIGNANT LA BALISE 1 AU POINT MILIEU 4 DU SEGMENT 2, 3. IL S'EXPRIME EN FONCTION DU DECALAGE DE PHASE ENTRE LES SIGNAUX RECUS PAR LES TETES 2 ET 3. L'INVENTION S'APPLIQUE NOTAMMENT AUX MESURES SOUS-MARINES A GRANDE PROFONDEUR.
