摘要:

数字射频存储器是电子战中较为行之有效的技术手段,它能通过对接收到的敌方信号进行不同的处理以实现对敌方雷达进行相应的干扰。由于雷达信号瞬时带宽的不断增大而使器件发展水平滞后,信道化DRFM技术的重要性变得日益突出。文中简述了DRFM的基本原理和信道化DRFM的方法,并用Matlab仿真验证了信道化DRFM的可行性,分析了通道数量对合成信号的质量的影响,为以后的工程中实现DRFM存储较高的瞬时带宽提供了理论基础。

Abstract:

Digital radio frequency memory technology is more effective in electronic warfare technology,and it could jam enemy radar correspondingly by different processing and modulation of the received hostile signal.As the radar signal instantaneous bandwidth increases,the importance of technology of channelized DRFM has become increasingly prominent.This paper describes the basic principle of DRFM and the method for DRFM channelization,verifies the feasibility of DRFM by Matlab simulation,and analyzes the influence of the number of channels on the quality of synthesized signals,which provides a theoretical basis for DRFM in later project to realize the storage of higher instantaneous bandwidth.

Key words: digital radio frequency memory;electronic warfare;channelized
