介绍了一种以3片ADSP_TS101芯片为核心设计的雷达信号处理系统。该系统中DSP芯片仅用链路口完成相互间点对点的通信,各自的数据总线互不相连,存储器空间地址彼此独立。系统具有硬件结构简单、体积小,程序易调试,整体可靠性高的优点。能实现雷达和、差信号的数字脉冲压缩与动目标检测,并控制着整个雷达系统的运行。该系统已经成功应用于实际工程中。

A real-time radar signal processing system is described,which is based mainly on three pieces of DSP chip ADSP_TS101.In the system,the DSP chips data bus are not connected and the programming memory address are independent from each other,only the link ports provide the communication channel for implementing point to point communications of the DSP chips.Thus,the system has some key features such as simple and efficient hardware circuit with small size,flexible software programming and debugging,and high reliability.It not only can implement the digital pulse compression and coherent integration for radar sum and difference signals,but also control the whole radar system.Furthermore,the system has beed successfully applied in engineering.
