| 中文摘要: |
| 本文介绍了一种用于拖曳线列阵声呐的压电陶瓷型水听器．我们在提高水听器工作稳定性与可靠性，并确保水听器有较高接收灵敏度的前提下，进行了水听器结构方案优化设计，以降低水听器的加速度灵敏度．研制的水听器接收灵敏度为-193dB，在20－1000HZ频段内灵敏度起伏为1．2dB，加速度灵敏度为-70dB左右． |
| 英文摘要: |
| A type of piezoelectric ceramic hydrophone used for towed line array sonar is presented in this paper- Along with improving the stability and the reliaboity, and ensuring high receiving sensitivity we carried out an optimum structural design of the hydrophone such that lts acceleration sensitivity is also low. The receiving sensitivity of the completed hydrophone is- 193dB, the undulation of the receiving sensitivity over the frequency range frorn 20 Hz to 1000 Hz is 1. 2 dB, while the acceleration sensitivity is about -70dB. |
