The invention discloses an adjustable subsurface buoy noise measurement system which comprises an underwater instrument cabin, a photoelectric transmission cable, an optical fiber hydrophone array, an unfolding device, mooring equipment and a water surface communication buoy. The optical fiber hydrophone array receives a target radiation noise signal in water and transmits the signal to the underwater instrument cabin through the photoelectric transmission cable; the underwater instrument cabin is fixed to the seabed through mooring equipment and connected with the water surface communication buoy. The unfolding device is fixed to the seabed through a hook anchor, and the optical fiber hydrophone array is adjusted through the unfolding device to achieve horizontal laying; the underwater instrument cabin and the unfolding device are of a positive buoyancy structure, and therefore a trapezoidal structure is formed underwater. According to the invention, the whole array is controlled to be horizontal underwater and the attitude of the array is stabilized by using the unfolding device to fold and unfold the photoelectric transmission cable and the hook anchor, and when the attitude of the array reaches the attitude required by equipment test, the unfolding device stops working, and at the moment, the equipment is in a silent state and does not generate any noise, so that the noise influence generated by the equipment can be reduced.
本发明公开了一种可调节式潜标噪声测量系统,包括水下仪器舱、光电传输线缆、光纤水听器阵列、展开器、系留设备、水面通信浮标;光纤水听器阵列接收水中目标辐射噪声信号,并通过光电传输线缆将信号传送给水下仪器舱;水下仪器舱由系留设备固定在海底,并连接水面通信浮标;展开器由钩锚固定在海底,光纤水听器阵列由展开器进行调节,实现水平布放;水下仪器舱和展开器为正浮力结构,由此在水下形成一个梯形结构。本发明利用展开器收放光电传输线缆和钩锚,来控制整条阵列在水下水平,稳定阵列姿态,当阵列姿态达到设备测试要求姿态后,展开器停止工作,此时设备处于静默状态不产生任何噪音,从而可以减少设备自身产生的噪音影响。
