采用基于中频注入的方法为雷达构建复杂电磁环境，对提高部队在复杂电磁环境下的作战训练水平具有重要意义。研究了一种基于中频注入的雷达信号模拟器的设计与实现，通过对目标回波、欺骗干扰信号和压制干扰信号分析，提出了模拟器系统的总体设计及模块化设计方案，并对该模拟器进行了实际测试。测试结果表明：该模拟器能够实时模拟目标回波、欺骗干扰信号及间歇瞄准式、阻塞式及扫频式等干扰信号，并且可以根据训练环境的需要选择信号输出，满足了设计指标要求，具有较高的实用价值。

It is very important to build up a kind of complex signal environments by adopting a method of IF injection to improve and train operators under conditions of the complex electric warfare environments. This paper introduces a radar signal environment simulator.First,through analyzing target echoes,decep-tion signals and jamming signals.an overall concept design and a modularization structure design plan for the simulator are proposed,and its performance is tested.The result shows that this simulator can gener-ate echo,deception jamming ,chirp jamming signal,barrage jamming,and interrupted??spotting jamming signal in real??time,and can switch over them in signal channels.The simulator has a great value for matc-hing the design requirement well,and has practical value.
