随着现代雷达技术的发展，采用计算机仿真技术和高速数字电路技术的各种目标和环境模拟器在雷达的开发研制过程中发挥了越来越重要的作用。该文简述了实时雷达电磁环境模拟器的基本组成，对不同需求时模拟器的实现方法进行了探讨。着重介绍了一种较大规模的实时雷达电磁环境模拟器，对该模拟器的组成、各部分的功能和实时信号产生的具体实现都作了详细的描述。

With the development of radar technology, the target and environment simulators which make use of computer simulation technique and high speed digital circuit technique play a more and more important role in the development of the radar. This paper describes briefly the basic composition of the real time radar electromagnetic environment simulator and discusses the implementation methods of different requirements. It introduces mainly one kind of large-scale real time radar electromagnetic environment simulator and describes in detail the composition of the simulator, the functions of every part and the specific implementation of real signal generlization.
