Study On Anti-interference Technique And Applied Research Of Pulse Doppler Radar

Since the Second World War, radar has become an important military detectionequipment, has the very high defense value, while at the same time, for the study ofelectronic jamming technology of radar performance failure is deepened gradually,development of the two electronic countermeasure we call (ECM) two aspects. In addition,in order to ECCM resistance to electronic interference (ECCM) technology has become anindispensable research branch in modern radar technology, electronic warfare (EW) is themost distinctive feature of modern war.Electronic warfare background, research and development of radar faces two majorproblems: one is how to ensure the survival of radar in hard hit conditions; the two is howto improve the ability of the radar anti-jamming, namely against each other for radarjamming (ECM) to improve its anti-interference ability (ECCM), there exists a certainrelationship between these two problems. ECCM and electronic warfare radar in radarECM is between two mutually opposite of dependence. They fight each other, constantlypromote each other. With the development of electronic technology, information technology,radar jamming and anti-jamming technology struggle between is becoming more and morecomplex.Into the20century70’s, the development of digital processing technology and largescale integrated circuit technology, has gradually been applied to each navigation, missile,satellite tracking, target range, fire control, meteorological fields pulse Doppler radar,played an important military role. At the same time, according to various interferencetechnology the technology also emerge as the times require. The pulse Doppler radar bygeneral anti-jamming technology, principle were researched and analyzed, studied on thepulse Doppler radar under different conditions of anti-jamming technology issues, so as tofurther enhance the accuracy of the pulse Doppler radar. In addition, this paper alsocombines the Interference of Doppler radar anti-jamming technology and developmentsituation, the future trend of the radar jamming and anti-jamming techniques are discussed.Based on the data access and combed the domestic and foreign related research, and onthe basis of research achievements, both at home and abroad, the research on radarjamming and anti-jamming technology were briefly reviewed in this paper. At the sametime for domestic and foreign research present situation has carried on the contrast, putforward the problems existing in the current research in China; For pulse doppler radar anti-jamming technology characteristics, the general principle and so on has carried on theresearch and analysis of pulse doppler radar in anti-jamming technologies under differentenvironmental problems are studied, so as to further enhance the accuracy of the pulsedoppler radar detection. In addition, this article also combined with doppler radar jammingand anti-jamming technology development present situation, for the future developmenttrend of radar jamming and anti-jamming technology is prospected.
