基于System Vue的PD雷达对抗仿真系统设计

Design of PD radar countermeasure simulation system based on System Vue

为了深入分析PD雷达对抗试验现象,获取各种对抗条件下对PD雷达信号处理链路的响应特性,利用SystemVue系统仿真软件和Matlab协同建模仿真,搭建了一套包含回波信号生成、干扰信号生成、天线特性模拟、杂波特性模拟、接收机、模数转换、MTD处理、CFAR检测等模块组成的PD雷达对抗仿真系统,该系统提供了高效、灵活、直观的仿真方式。通过脉冲干扰信号的仿真测试表明,系统具备了开展不同对抗条件下链路响应特性研究的能力,为PD雷达对抗试验评估提供了有力支撑。

To deeply analyze the experiment phenomenon of PD radar countermeasure, and acquire the response characteris- tic of PD radar signal processing link under different confrontation conditions, a set PD radar countermeasure simulation system composed of echo signal generation module, interference signal generation module, antenna characteristic simulation module, clutter characteristic simulation module, receiver module, A/D conversion module, MTD processing module and CFAR detec- tion module was constructed by means of system simulation software SystemVue and Matlab for collaborative modeling and simu- lation. The system provides an efficient, flexible and intuitive simulation mode. The results of pulse interference signal simula- tion test show that the system has the ability to study the link response characteristic under different confrontation conditions, and provides a powerful support for the assessment of PD radar countermeasure test.
