水下信息感知系统及其关键技术

Underwater Information Perception System and Key Technologies

摘要:

水下信息感知是指水下系统通过声、光、磁、电等传感器接收海洋环境和目标信号，经过信号处理，获得海洋环境和目标特征信息的过程。由于声波能在海洋中远距离传播，水下声场信息感知受到格外重视。水下信息感知的最终目的是发展大范围海洋水下监测系统，通过信息感知，掌握海洋环境变化的规律， 建设透明海洋，为人类开发利用海洋服务。

Abstract:

Underwater information perception is a process of gathering sea environment and target signal with acoustic，optical，magnetic，electrical and other sensors，processing the signal and obtaining the characteristics of the sea environment and target. Since the sound wave can transmit over a long range in water，the acoustic information is paid extraordinary attention. The final purpose of underwater information perception is to develop ocean underwater surveillance system，understanding the principles of ocean environment variance，constructing the transparent ocean，and serving the people for exploiting the ocean.
