Research On Methods Of Radar Anti-active Deception Jamming

Active deception jamming is a widely used interference. The use of false targets and the role of informations in radar target detection and tracking system, so that the radar does not correctly detect the real goal, or can not correctly measure the true objective of the parameter informations. Therefore, the study of its confrontational approachs is of great importance.In this paper, the status and trends of radar anti-jamming are made a brief introduction, and then all kinds of active deceptions include:distance deception jamming, speed deception jamming, distance-speed synchronous towed jamming, angle deception jamming, electronic false targets fraud jamming, active decoy deception jamming and other cheating methods, are researched resulting from the principle. For anti-active deception jamming methods,include:Kalman filtering method of anti-range deception jamming; wavelet decomposition method of anti-speed deception; spectrum identification method of Anti-distance-speed synchronous towed; micro-doppler feature extraction law of anti-active decoy deception, this paper carries out detailed introduction and study, and verify that these types of methods can be implemented and correct through simulation and analysis. This paper makes a brief introduction of radar anti-jamming efficacy evaluation as well as simulations and analysis of the anti-jamming improvement factors and multiple false targets are carried out, and put forward several evaluation methods, and some problems.
