Abstract

Underwater towed antenna comprises a flexible tube (17) filled with filler (23) in which a large number of hydrophones (18) are serially arranged. The hydrophones are supported against the tube casing (171) and are held approximately in the center of the tube by radial prongs (19) extending from the surface of the hydrophones. The filler material can by polyethylene, polyurethane and can have carbon fiber reinforcement. The prongs and casing (20) of the hydrophones are made of a gel material.
