Methods for making linear acoustic antennas designed to be towed behind a boat, wherein open-cell foam cylinders (101) are opened lengthwise (103) and electroacoustic receiver modules (101) are placed therein. After closing the cylinders, they are arranged end-to-end and a series of layers of porous nonwoven material, reinforcing nets (111) and wiring cables are wound around the cylinder surfaces. Finally, a protective sheath is extruded onto the cylinders and their end portions are joined together. The manufacture of such antennas may thus be mechanised using cable technologies.
