摘　　要：总结了雷达系统仿真的技术现状,指出了基于传统仿真软件建模与仿真的缺点及Simulink在雷达系统仿真中的优势。以雷达系统中的混频器为例,介绍了如何利用Simulink对其进行建模和仿真,并给出了仿真结果和分析。仿真方法具有模型设计过程简单、修改容易和结果直观等特点。该文的工作不但克服了在工作站上用SPW等系统仿真软件进行雷达系统仿真投入大、推广难的不足,又克服了利用高级语言编写雷达系统软件通用性差、难度高、周期长的缺点。为今后在Simulink上开发大规模雷达系统仿真模型库和仿真复杂雷达系统打下基础。Actual state of radar system simulation technology is concluded in this paper, the disadvantages of simulations based on the traditional simulation software and the advantages of simulations based on the Simulink software are indicated. Taking the mixer of radar system for example; this paper introduces how to make modeling and simulation using the Simulink with the results and analysis presented. The advantages of such method include the model can be easily designed and modified and the data can be visualized. Simulation on Simulink can overcome not only such disadvantages as large investment and hard popularization of that on SPW, but also the disadvantages as properties of complexity, difficulty and lengthiness in the traditional method using advanced program languages. This lays foundation for the development of large radar model library and simulation of complex radar system based on Simulink.
