基于水下滑翔机的海洋环境噪声测量系统

摘要

Autonomous underwater glider (AUG) is a new type of submersible vehicles and has a great potential for application to survey the ambient sea noise. In this paper, "Petrel II" glider is chosen as the experimental carrier and deep-water hydrophone and data acquisition system is designed and developed for it. The deep-water hydrophone has the characteristic of strong pressure resistance and high sensitivity, which has been tested with 60 MPa stress, and the data acquisition system has the characteristic of small size, low power consumption, flexible control and easy to extend. Successful tests in basin and a sea area verify the feasibility of technical scheme and the stability of system work, and this platform can be used for in-depth experimental study of spatial-temporal characteristics of ambient noise.%水下滑翔机是一种新型的水下潜器,将其用于海洋环境噪声测量具有很大的应用潜力.选择的平台是"Petrel II"滑翔机,为其设计和实现了深水水听器和数据采集系统.深水水听器具有耐高静水压和高灵敏度的特点,并通过了60 MPa的高静水压力试验;数据采集系统具有体积小、功耗低、控制灵活和易于扩展的特点.搭载声学测量系统的滑翔机顺利通过水池测试和海上试验,测试结果验证了技术方案的可行性和系统工作的稳定性,可为深入进行海洋环境噪声时空特性实验研究提供技术支持.
