Title
(EN) METHOD AND EQUIPMENT FOR MINE DETECTING
(FR) PROCEDE ET EQUIPEMENTS DE DETECTION DE MINES
Abstract
(EN)
A method and an equipment for mine detecting in the waters by using an acoustic wave transmitter (11, 3) and a receiver (11, 18) of acoustic waves reflected from an object in the water, on the bottom or under the bottom of the water. The transmitter and receiver are placed in a vessel sailing on a fairway. The vessel where the transmitter (11, 3) and the receiver (11, 18) have been placed is a semi-submersible vessel.
(FR)
Un procédé et des équipements servant à la détection de mines dans l'eau au moyen d'un émetteur d'ondes acoustiques (11, 3) ainsi qu'un récepteur (11, 18) d'ondes acoustiques réfléchies par un objet dans l'eau, au fond ou sous le fond de l'eau. L'émetteur et le récepteur sont placés sur un vaisseau qui navigue sur un chenal. Le vaisseau sur lequel ont été placés l'émetteur (11, 3) et le récepteur (11, 18) est un vaisseau semi-submersible.
