摘要
声速是海洋声呐测量中最重要的声学参数之一。拖缆式声速剖面仪可提供实时测量功能,但其缆长不能满足深海测量要求;自容式声速剖面仪可满足深海测量要求,但工作效率低。如何提高野外深海声速剖面测量工作效率是深海调查一项非常有意义的工作。文中详细介绍了基于声学调制解调器的声速剖面遥测系统的主要结构和功能,揭示了水声通信技术在深海非铠装缆测量中的应用优势。
The sound velocity is one of the most important acoustic parameter in ocean sonar. The cable SVP has the real-time measurement function, but it is not enough cable for deep depth ocean. Automatic measurement has 5000m range, but the work efficiency is not ideal. How to increase the work efficiency of SVP measurement is significant work. The article introduces the configuration and function of SVP remote measurement system which base on the acoustic modem in detail. Finally open out the advantage of underwater acoustic communication technology in deep-sea measurement.
