DRFM干扰在OFDM新体制雷达中的研究
Research on DRFM Jamming in OFDM New System Radar
摘要
Abstract
The new system radar uses orthogonal frequency division multiplexing(OFDM)digital modulation as the radar signal source,which has the advantages of high frequency spectral efficiency and high resolution.This article firstly introduces the basic components of the new system radar,mainly including OFDM signal source,transmission module,environment module,receiver module and signal processing module.Secondly,the main components and work-ing principles of digital radio frequency memory(DRFM)interference are introduced,including false target jamming.Finally,the DRFM jamming is combined with the new system radar,and the ranging and speed measurements on simu-lated targets are carried out under two conditions:with and without jamming.The results confirm the accuracy of the tar-get measurement using the new system radar and show that DRFM jamming is feasible.It has reference significance for the research of new system radar and DRFM interference.关键词
