| 摘 要： | 报道了光纤水听器用于拖曳线列阵的研究结果。在保证光纤水听器声相位灵敏度的前提下, 优化设计了光纤水听器的结构,降低了光纤水听器的加速度灵敏度36dB。实验测得在20-1600Hz 频段,该光纤水听器的相位灵敏度为-162．7dB,频段内灵敏度的起伏为±0．7dB,加速度灵敏度小于-30dB。

| Abstract: | A type of fiber optic hydrophone to be used for towed line array is presented in this paper. The acoustic phase sensitivity being ensured, an optimum structural design of the fiber optic hydrophone is proposed to reduce by 36dB its acceleration sensitivity. Over the frequency range from 20Hz to 1600Hz,the acoustic sensitivity of the fiber optic hydrophone is-162.7dB with undulation of 1.4dB, while the acceleration sensitivity is not greater than -30dB. |
