Abstract
For improving sensitivity of towed receiving hydrophone, carry out improvement and research of hydrophone performance. The electroacoustic performance of towed receiving hydrophone is simulated by finite element, replace the plexiglass cover plate with the copper plate and adding cork rubber liners in piezoelectric ceramics circular tube. Then compare and analyze the performances before and after improvement. The result shows that the undulation of sensitivity can be improved less than 4 dB, while the directivity of the receiving hydrophone change less. By improving the design, it can greatly reduce the sensitivity fluctuation receiving hydrophone, which can simplify the post stage circuit, and improve the dynamic range of the system.关键词
