摘要/Abstract

摘要： 传统同振式矢量水听器在水下缓动声纳平台应用时，自身姿态变化难以准确测量，导致目标测向精度低，为此开展了二维复合同振式矢量水听器研究。分析二维矢量水听器姿态实时测量与校正原理，选取微机电系统姿态传感器作为姿态感知器件，设计具备姿态测量功能的二维复合同振式矢量水听器，并实现其在Argo浮标平台的集成应用。海上试验结果表明：同振式矢量水听器可在10~3000Hz范围内采集声场信息，矢量通道具有余弦指向性，在1 kHz频点处灵敏度为-179.5 dB （0 dB参考值为1 V/μPa)，声压通道灵敏度级为-191.5 dB±0.5 dB(0 dB参数值为1 V/μPa)，具备姿态测量功能；同振式矢量水听器应用于浮标平台进行海洋环境噪声与水中目标同步监测技术可行，为其在水下缓动声纳平台工程化应用奠定了基础。

Abstract: The traditional co-vibration vector hydrophone is difficult to accurately measure the attitude change in the underwater slow-motion sonar platform, which leads to the low measuring accuracy of target direction. The attitude real-time measurement and correction principle of vector hydrophone are nalyzed, and a MEMS attitude sensor is selected as attitude sensing device. A two-dimensional combined co-vibration vector hydrophone with attitude measurement function was designed, and its integrated application on the Argo buoy platform was realized. The results show that the co-vibration vector hydrophone can collect sound field information in the range of 10-3 000 Hz. Vector channel has cosine directivity with sensitivity of -179.5 dB at 1 kHz (0 dB=1 V/μPa). Sound pressure channel sensitivity is -191.5 dB±0.5 dB (0 dB=1 V/μPa). The co-vibration vector hydrophone is applied to the buoy platform for synchronously monitoring the marine environmental noise and underwater target, which lays a foundation for its engineering application in the underwater slow-motion sonar platform.
