摘　　要：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.
