大深度工作环境下，静水压会引起分布反馈式光纤激光水听器反射中心波长漂出解调系统的复用窗口，使水听器无法解调目标声压信号；不同的静水压也会引起分布反馈式光纤激光水听器灵敏度的变化，影响光纤激光水听器阵列的一致性。基于电力声类比理论，提出带静压补偿的分布反馈式光纤激光水听器探头，建立结构的声压传递函数，分析各结构参数对传递函数的影响，为分布反馈式光纤激光水听器探头频率响应平坦化设计提供理论依据。加工制作了耐静压分布反馈式光纤激光水听器样品进行测试，在0 kHz～10 kHz频率范围内声压灵敏度波动范围不大于±2.4 dB，2.3 MPa内出射激光中心波长漂移量不大于0.06 nm，对深水光纤激光水听器的研究具有指导意义。

In the deep working environment, the hydrostatic pressure can cause the reflection center wavelength of distributed feedback (DFB) fiber laser hydrophone drifting out of the multiplexing window of demodulation system, and the target sound pressure signal cannot be demodulated by the water receiver; different hydrostatic pressures also cause changes in the sensitivity of the distributed feedback fiber laser hydrophone, which affects the consistency of the fiber laser hydrophone array. Based on the theory of electric sound analogy, a distributed feedback fiber laser hydrophone probe with static pressure compensation was proposed. The sound pressure transfer function of the structure was established, and the influence of various structural parameters on the transfer function was analyzed, which provided a theoretical basis for the flattening design of the frequency response for distributed feedback fiber laser hydrophone probe. The resistant static pressure distributed feedback fiber laser hydrophone sample was processed and tested. The fluctuation range of sound pressure sensitivity was no more than ±2.4 dB in the frequency range of 0 kHz～10 kHz, and the wavelength drift of the exiting laser center within 2.3 MPa was no more than 0.06 nm. The results are of guiding significance for the research of deep water fiber laser hydrophone.
