Abstract
L'INVENTION CONCERNE UN DISPOSITIF DE MESURE DE COURANTS AQUATIQUES PLACE SUR UN BATEAU EN MOUVEMENT COMPORTANT UN SONAR A EFFET DOPPLER. LE DISPOSITIF COMPORTE DEUX GROUPES DE TRANSDUCTEUR 2 ET 3 EMETTANT ET RECEVANT SUIVANT LES DIRECTIONS D, D, D ET D FAISANT L'ANGLE A AVEC LA VERTICALE Z. UN CIRCUIT D'EMISSION FOURNIT DES IMPULSIONS SIMULTANEMENT A DEUX FREQUENCES F ET F. LE CIRCUIT DE RECEPTION 4 TRAITE LES SIGNAUX D'ECHOS DE REVERBERATION EN VOLUME AFFECTES DE L'EFFET DOPPLER, CORRESPONDANT AUX FREQUENCES F ET F AINSI QUE L'ECHO PAR LE FOND AFFECTE DE L'EFFET DOPPLER A LA FREQUENCE FF-F, CETTE FREQUENCE ETANT GENERE PAR SUITE DES NON-LINEARITES DU MILIEU. LE CIRCUIT 7 FOURNIT LE PROFIL DES VITESSES HORIZONTALES DES COURANTS PAR TRANCHES. APPLICATION AUX COURANTOMETRES EN GRANDE PROFONDEUR UTILISES EN PROSPECTION PETROLIERE ET EN NAVIGATION.
