摘　　要：电子对抗系统是一个具有完善的电子侦察、电子进攻和电子防御的电子武器系统。研制并开发一种工作频带宽、信号适应能力强、可扩展性好的综合电子对抗设备是现代电子对抗的必然要求。软件无线电技术的兴起为解决这一难题提供了最佳途径。首先介绍了软件无线电的基本思想和核心概念,然后详细探讨了以软件无线电为核心的电子对抗侦察接收机和电子对抗干扰发射机的组成以及工作原理,并提出了在应用中所要注意的问题。Electronic countermeasure system is an electronic weapon system with sophisticated electronic reconnaissance, electronic attack and electronic defence capability. It is necessary to investigate and develop an integrated electronic countermeasure equipment with wide frequency bandwidth, adaptability and expansibility. The technology of Software Radio provides an optimum method to solve this problem. First the basic and key concept of Software Radio are introduced in this paper. Then on the basis of Software Radio the principle of electronic countermeasure reconnaissance receiver and jammer are discussed in detail. Finally the points which should be considered in practice are also provided.
