摘要:

数字射频存储器(DRFM)能保持干扰信号与雷达信号的相参性,是干扰新体制雷达的重要技术手段。文中介绍了DRFM的基本原理和纯信道化DRFM的实现方式,并通过仿真分析了信道数目、信道重叠带宽和拼接方式对信号合成质量的影响,为在工程中实现宽带DRFM系统提供了理论依据。

Abstract:

Digital radio frequency memory (DRFM) technology can keep jamming signals being coherent with radar signals,and it has become an important method to jam new system Radar.In this paper,the fundamental principle of DRFM and the implementation of channelized DRFM are introduced.In addition,the impact of the number of channels,the overlap bandwidth of channels and the synthesis method of signals on the quality of signal synthesis is analyzed in detail by simulation.It also provides a theoretical basis for the broadband DRFM system.

Key words: DRFM;digital channelization;signal synthesis
