雷达电子战系统电磁环境仿真

电磁环境仿真是设计、准确评估雷达电子战设备战技指标的基础。该文阐述了雷达电子战系统电磁环境仿真的基本概念以及建立典型电磁环境应遵从的准则。讨论了三种典型的电磁环境仿真方法以及各自的优缺点。提出了一种对电磁环境进行信号仿真的方法，其中雷达辐射源的载频、脉宽、重频等主要描述参数都由一组数据表示，可以反映出多种类型复杂的脉冲方式，在此基础上建立了可以体现不同体制雷达信号的仿真模型，仿真实现了典型雷达电子战战场态势下的雷达电磁环境。仿真结果在实际应用中证明是有效的。

Electromagnetic Environment Simulation for Radar EW System

At present electromagnetic environment simulation is a fundamental work in designing and evaluating the performance of radar EW system.This paper first introduces the concepts of electromagnetic environment simulation for radar EW system,then proposes several rules of designing typical electromagnetic environment.Three methods of electromagnetic environment simulation and each methods' advantage and disadvantage are discussed.A signal simulation method for electromagnetic environment is developed.These radar parameter models ,which utilize a group of data to describe the important radar parameters such as RF,PW,PRI, can simulate different system radar signal.The simulation software is used to create an electromagnetic environment under typical radar EW scene.The results of the simulation show that this method is effective.
