TOWED STREAMER HYDRO-ACOUSTIC MODULE AND METHOD OF ITS MANUFACTURE Russian patent published in 2018 - IPC G01V1/38 

FIELD: antenna equipment.

SUBSTANCE: invention relates to the marine flexible extended towed antennas equipment serving to measure the sound field in water and used in geophysics and hydro acoustics. In the hydrophone module, acoustic pressure receivers are rigidly connected by a kapron thread, at which ends rectangular printed circuit boards are fixed. Resulting chain is pulled through the hose measuring section so that the printed circuit boards ends and nylon threads extend beyond the hose, after which the hose ends are sintered under the press to form a sealing seam. At that, the final hose sections, the normal planes of the printed circuit board, take the shape of a conical profile.

EFFECT: this hydrophone module design is light, technological and allows to reduce the hydrophone module sensitivity to longitudinal vibration by reducing the fluid flow effect in the towed streamer at the ends of the hydrophone module.
