Abstract
L'antenne acoustique de l'invention comporte au moins un capteur surfacique formé d'un empilement de couches conductrices et de couches diélectriques en matériau piézoélectrique enfermées dans un enrobage de matériau souple, l'ensemble ainsi constitué formant un panneau plat (2) monté contre la coque (5) d'un bâtiment naval, ce panneau épousant la forme de cette coque. Le montage du panneau sur la coque est obtenu au moyen de deux profils de rive (3, 4) carénés, en laissant subsister une lame d'eau intercalaire (6) entre panneau (2) et coque (5). Avantageusement, l'enrobage comprend une enveloppe de matériau souple remplie d'un matériau de garnissage viscoélastique. Le matériau piézoélectrique des couches diélectriques du capteur est de préférence un film de polyfluorure de vinylidène.
