摘　　要：雷达,雷达对抗课程的教学,需要有一套经济实用并且行之有效的实验设备,本文介绍的由西电电子对抗研究所所研制的雷达/雷达干扰实验仪就可以满足这一要求。本文简单分析了雷达/雷达对抗试验仪的功能和组成。雷达/雷达对抗试验仪是《雷达原理》、《雷达对抗原理》理论教学的重要补充,提供了实践教学的手段。实验仪采用了DDS信号产生技术,数字信号处理(DSP)技术和正交调制技术(QAM),能够完成多个雷达和雷达对抗试验,包含了雷达信号中频、视频处理模块和雷达干扰信号产生模块,同时还具有良好的可扩充性。雷达/雷达对抗实验仪的研制和使用,起到了较好的教学目的,填补了国内高校相关示教仪器的空白。The teaching of the course of radar and radar countermeasures requires a set of equipment whose price is relatively low. In this paper, we introduce an instrument for the experiments of radar/jamming of radar which invented by Institute of Electronic courrtermeasures of Xidian university can achieve the demand. In this paper, the function and the composition of the instrument is analysed. The instrument for the experiments of radar/jamming of radar is an important supplyment of the teaching of《The principle of radar》and《The principle of radar countermeasures》, providing the tools of instruction and practice. The equipment adopt the technique of DDS （ Direct Digital Synthesis） signal generate ,digital signal processing （DSP） and quadrature modulation （QAM）, provide several experiments of radar/jamming of radar, consist of modules of intermediate frequency generator, video signal processing unit and radar jamming signal generator, and have the advantage of expansion, The research and use of the equipment get to the purpose of teaching and fill the gaps of the related demonstrating apparatus in domestic university.
