水声学与海洋工程

UNDERWATER ACOUSTICS AND OCEAN ENGINEERING

声波是唯一能在海水中远距离传播的信息载体，在海洋环境观测、海洋测绘和资源勘探、水下定位、水下通信中起了重要作用．文章介绍了水声学研究的对象和它的特点，综述了水声信道、声系统及水声信息检测识别等方面研究的最新进展．在２１世纪———海洋世纪，水声学将在海洋工程中作出更大贡献．

Acoustic waves are the only information carrier which can propagate long distances in sea water.Underwater acoustics plays an important role in ocean environment observation,bottom surveying,resources prospecting,underwater navigation and underwater communication.After an introduction to the basic features of underwater acoustics the latest progress in R&D of underwater acoustic channels,acoustical systems and detection/recognition of underwater acoustic signals are reviewed.Underwater acoustics will contribute greatly to ocean engineering in the 21st century.
