针对雷达电磁环境仿真研究，采用脉冲描述字对雷达电磁环境进行描述，运用功能仿真方法对雷达电磁环境进行了仿真。首先构建了固定载频、载频跳变；固定脉宽、捷变脉宽；固定重频、重频抖动等雷达信号特征参数数学模型；然后以信号特征参数模型为基础，对雷达常规脉冲信号模型进行设计；最后给出了实体雷达模型TRAC 2000N中典型信号模型的模拟生成实例。该雷达电磁环境仿真方法可为电磁环境仿真研究提供参考。

This paper describes the radar’s electromagnetic environment (EME) by using the pulse descrip-tion word (PDW) and simulates the radar’s EME by taking up the method of functional simulation, in terms of the simulation study of radar’s EME. Firstly, the math models for the radar’s signal characteristics parameters are con-structed, including the fixed carrier frequency and its hopping, the fixed pulse-width and its agility one, the fixed repetition frequency and its jittering and others, based on which, a model of radar ’s conventional pulse signal is designed, and finally, the simulation-generated example of typical signal model in the model of entity radar TRAC 2000N is given in this paper. This proposed simulation method of radar’s EME can be a reference for the simulation study of EME.
