摘要：

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. © 2020, Editorial Board of Acta Armamentarii.
