基于合作信标的水声跟踪数字信号处理系统设计

Digital Signal Processing System Design of Underwater Acoustic Tracking Base on Cooperative Beacon Signal

高速数字信号处理系统作为水声跟踪测量系统的核心设计部分,在合作信标水声跟踪应用中,基于实时性的考虑,系统采用了FPGA和DSP结合设计。论文给出了系统硬件设计框图,并详细介绍了该软件设计流程及接口设计。通过湖上水声跟踪试验,验证了系统设计的实用性、可靠性,且该系统现已投入工程应用,取得了明显的经济效益。

High speed digital signal processing system is the core part of the underwater acoustic tracking and measur ing system. According to the cooperative beacon underwater acoustic tracking application, based on the consideration of real- time, the system uses FPGA and DSP combination design. This paper gives structure diagram of the hardware system, and introduces the software design process and interface design. By underwater acoustic tracking test on lake, the practicability, reliability of system design are verified, and the system has been put into engineering application, which achieved significant economic benefit.
