摘要: The disclosure concerns a directional hydrophonic antenna, consisting of several pairs of dipoles formed by omnidirectional hydrophones superimposed in a streamer and keeping the same reference angle for all the pairs of dipoles. The goal sought is achieved by means of a chain of superimposed, directional modules each bearing a hydrophonic sensor on each lateral face and joined by ringed tubular elements through which there goes a central rod made of fiber glass and a strand of electrical connection cables.

摘要: A vibration damper is provided for a towed body usable more particularly as head section of an underwater antenna towed by a boat and containing detection and measuring instruments.The damper of the invention comprises at least one piece with high loss angle in contact with a traction element so that vibrations perceived by the traction element cause deformations of said piece.
