摘要
提出了一种将测振传感器与前置电路集成为一体的振速水听器敏感结构。通过对振速水听器及其信号调理电路输出电噪声的精细分析,针对前置电路匹配电阻热噪声、运放内部噪声、接地共模噪声、线缆接触噪声等不同噪声的产生根源,采取一系列噪声抑制与防治措施。在引入新型电路板材料实现一件多用的基础上,提出一种振速水听器内部传感器及电路的组装方式。试制样机的实际测试结果表明,采用新型集成化结构的振速水听器静态输出噪声与直流电压偏移被控制在较低的数量级。
A velocity hydrophone sensitive structure with integrated vibration sensor and pre-amplifier is proposed in this paper. By detailed analysis of output noise from velocity hydrophone and signal conditioning circuit, a series of noise suppression and prevention measures were taken to reduce the pre-matched resistance hot noise, inner noise in operational amplifier, grounding common-mode noise, and cable contact noise. On the basis of a aluminum base material, an assembly manner of inner sensor and circuit in the velocity hydrophone is proposed. The test results show that, the static output noise and the direct current offset is low, and the directivity of the velocity hydrophone is fairly good to approach "8" shape
