Signal Feature Extraction Methods of Radar Anti-deception Jamming
摘要
Abstract
Since the features of jammer are similar to that of target echoes, the deception jamming poses a most serious threat to military radar. Therefore, there is an urgent need for new radar anti deception jamming methods. In order to accomplish radar anti deception jamming, it is necessary to analyze and extract the different features of the deception jamming and target echo. The mathematical models of deception jamming and target echo are given and studied firstly, then the differences in the amplitude undulation features, high order cumulant features and bispectrum features between the deception jamming and target echo are compared. Based on the results of feature analysis, the feature extraction methods applied in radar anti deception jamming are proposed and three feature factors are defined, then the feature parameters aggregate is built. Finally, the feature extraction methods are verified with simulation and real data in an actual deception jamming experiment.关键词
