The number of array elements of the linear array is usually large, the number of cores of a main signal transmission cable is large, and a common oil filled cable or gel filled solid cable signal transmission line is separated from a hydrophone by a certain distance and passes through the side surface, so that the influence of the transmission line on the sound wave shielding to the receiving directivity of the hydrophone is avoided, the outer diameter of the whole array cable is enlarged, and the use difficulty is improved. The other cable array solution is to install the hydrophone at the side of the main cable of signal transmission and to pay a certain distance, so as to avoid the influence of the main cable on the sound wave received by the hydrophone, thus increasing the manufacturing difficulty and the manufacturing cost of the cable array and bringing trouble and potential safety hazard to use.
For the noise floor requirement of the array cable, two solutions exist, one is to add a vibration reduction section of several tens 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 the signal transmission cable needs to pass through the vibration reduction section, the crosstalk and attenuation between signals can be larger, which contradicts with the original purpose of improving the received signal, and the cost of the array cable is obviously increased. The other method is to bind a ribbon with a certain length on the outer side of the main cable, and the ribbon can also generate a certain noise reduction effect, but is limited by the width of the ribbon, the mounting density is limited, and the ribbon length is lengthened under the condition that the ribbon density is limited, so that the effect of reducing the noise floor of the array cable can be achieved, but the ribbon is not suitable to exceed 20cm because of the risk of intertwining and damage.
