摘　　要：数字信号处理系统是水下目标主动跟踪系统的核心,采用了数字信号处理器(DSP)和现场可编程门阵列(FPGA)设计了数字信号处理硬件系统,给出了硬件框图,介绍了各个组成芯片的功能,解决了DSP的硬件资源分配问题,完成了存储器接口设计、电源与散热设计以及FPGA接口逻辑设计。硬件平台具有强大的数字信号处理能力,合理的FPGA接口逻辑简化了DSP软件设计任务。试验结果表明,信号处理平台能够实时完成水下双目标信号的时延估计,估计精度高,满足了水下目标主动跟踪系统的要求。Digital signal processing system is the most important part in underwater target tracking system. This paper presents the hardware design of the signal processing system based on the high-speed digital signal processor （DSP） TS201 and field programmable gate array （FPGA）. The block diagram of the hardware platform is given and the chips used in the system are introduced. The distribution of the DSP hardware resources is discussed. The designs for the interface between DSP and FLASH, the power supply and cooling device and the FPGA interface logic are performed. The hardware platform provides high performance digital signal processing, and the DSP software design task becomes easier through the proper FPGA interface logic. The experimental result shows that the hardware system can accomplish the time delay estimation of two underwater targets with high preci- sion, and can meet the requirements of underwater target tracking system.
