| Analysis of radar jamming signal is not only the premise and foundation of jamming signal recognition, but also the guarantee of electronic anti-protection equipment to work effectively. Research on the analysis of radar jamming signal technology has great military importance and research prospects.Firstly, the classification and generation method of active radar jamming signal are introduced in this paper, then the current commonly used oppressive jamming signals’ and deception jamming signals’ Mathematical model are analyzed, and then the jamming signal and its modulation characteristic parameters are proved by simulation in the Matlab environment. Secondly, the technology of jamming signal receiving and detecting with signal receiver/signal processor is researched, detecting methods as well as analysis technology of jamming signal are discussed in the different receiving conditions. Finally, the method of time-frequency analysis and high order statistic analysis are introduced in this paper. The advantages and disadvantages of several time-frequency analysis methods is compared in jamming signal analysis application, then good effect analysis methods is selected to analysis of the effect of jamming signal feature extraction, and then the higher order statistics analysis in the application of deception jamming recognition is verified. |
