摘　　要：提出一种雷达视频信号模拟器的通用模块化结构 ,采用高性能的计算机和通用数字信号处理器构成 ,降低上层算法和底层硬件之间的关联程度 ,使得系统具有良好的通用性和实时性。讨论了在模块化设计中需要注意的主要问题 ,并以某脉冲多普勒雷达的模拟器为例 ,对这种结构进行了具体说明。但由于雷达信号处理的特点 ,模拟器还不能很简易地实现仿真能力和功能的扩展 。A general modular structure of radar video signal simulator is presented,which is composed of high performance computer and general digital signal processor. It reduces the correlation between the upper algorithm and the bottom hardware, thus improving the generality and real time ability of the system. The main problems requiring more attention in the modular design are discussed, and a detailed explanation of the structure is given with the simulator of a pulse compression radar as an example. The simulation ability and functions of the simulator can not be easily extended because of the characteristics of radar signal processing, which is yet to be solved.
