A sonar system includes a towfish comprising a first body linked to a second body, the first body being elongate along a longitudinal axis and comprising a plurality of acoustic transmitters distributed along the longitudinal axis, the sonar system comprising a cable linked to the second body and via which a surface carrier ship is intended to tow the towfish, the first body being mounted to pivot, with respect to the second body, about an axis of rotation so that, the first body can switch, by pivoting with respect to the second body about the axis of rotation, from an operational position to a capture position; the axis of rotation being substantially an axis of movement of the towfish, the longitudinal axis being substantially vertical in the operational position of the first body and being substantially horizontal in the capture position of the first body, when the towfish is totally submerged and towed by the carrier ship.

Sonar system

An active towed sonar comprises an emission antenna integrated into a submersible object called a towfish, a submersible receive antenna called a streamer and a tow cable to tow the towfish and the streamer. The tow cable comprises a termination connected mechanically and electrically to the streamer. The termination comprises means of removable mechanical and electrical connection of the towfish to the tow cable, independently of the connection of the streamer.
