| Abstract: | A type of piezoelectric ceramic hydrophone used for towed line array sonar is described in this article. On improving the stability and the reliability of the hydrophone and also ensuring its higher receiving sensitivity, we analyse the principle and the method of reducing the acceleration sensitivity of hydrophone in detail. A sample hydrophone has been designed accordingly. The receiving sensitivity of this sample hydrophone is -193.5dB and the undulation of the receiving sensitivity over the frequency band from 20Hz to 1000Hz is ±0.4dB,the acceleration sensitivity is about -65dB. |
