Abstract

APPAREIL COMPRENANT DEUX CANAUX A TRAJECTOIRES ACOUSTIQUES ORIENTEES A ANGLE DROIT AFIN DE MESURER LES COMPOSANTES ORTHOGONALES DE LA VITESSE D'UN COURANT. CHAQUE CANAL COMPREND DEUX TRANSDUCTEURS ORIENTES SUR UN MIROIR ACOUSTIQUE DE MANIERE QUE LE SIGNAL REFLECHI ET PROVENANT DE CHAQUE TRANSDUCTEUR ATTEIGNE LE TRANSDUCTEUR OPPOSE. UNE SALVE D'ENERGIE ACOUSTIQUE A HAUTE FREQUENCE EST EMISE PERIODIQUEMENT ET SIMULTANEMENT PAR LES DEUX TRANSDUCTEURS. UNE CIRCULATION DU COURANT DE LIQUIDE PRODUIT UN DEPHASAGE ENTRE DES SIGNAUX RECUS QUI EST REPRESENTATIF DE LA VITESSE DU COURANT. LE SIGNAL DE SORTIE PRODUIT PAR CHAQUE TRANSDUCTEUR EST MELANGE AVEC UN SIGNAL COMMUN DE REFERENCE DE MANIERE A OBTENIR DEUX SIGNAUX DE BATTEMENT A BASSE FREQUENCE DONT LA DIFFERENCE DE PHASE EST PROPORTIONNELLE A LA VITESSE DU COURANT. APPLICATION A LA MESURE DE LA VITESSE DE COURANTS MARINS.
