Background

The hydrophone array system is widely applied to the field of underwater acoustic engineering, is mainly applied to picking up underwater environment noise information and target sound information, and is two focuses of paying attention to reducing background noise of a receiving array cable and improving the use convenience of the array cable. The array element number of the conventional linear array is more, the signal transmission main cable has more cores, and the common oil-filled cable or gel-filled solid cable signal transmission line passes through the hydrophone from the side surface at some distances away from the hydrophone, so that the phenomenon that the transmission line shields sound waves to generate adverse influence on the receiving directivity of the hydrophone is avoided, the outer diameter of the whole array cable is increased, and the use difficulty is improved. The other cable array solution is to install the hydrophone at the side of the main cable for signal transmission and to spend a certain distance to avoid the main cable from influencing the sound wave received by the hydrophone, but this increases the manufacturing difficulty and cost of the array cable and brings trouble and potential safety hazard to the use.

Aiming at the requirement of reducing the background noise of the array cable, two solutions are provided, one is to add a vibration reduction section of dozens of meters at the front end of the array cable, the longer the vibration reduction section is, the more obvious the vibration reduction effect is, because a signal transmission cable needs to pass through the vibration reduction section, the crosstalk and attenuation among signals can be larger, which is contradictory to the original intention of improving the received signal, and the cost of the array cable is obviously increased. The other method is that a certain length of ribbon is bound outside the main cable, a certain noise reduction effect can be generated, the range is limited by the width of the ribbon, the adding density is limited, the length of the lengthened ribbon can also achieve the effect of reducing the background noise of the array cable under the condition that the density of the ribbon is limited, and the long ribbons are wound mutually and damaged, and are not suitable to exceed 20 cm.
