Researchon Protection Technology Against Complex Electromagnetic Environment For Airborne Guided Weapon

The electromagnetic environment for airborne guided weapons is getting more and more complexwith the rapid development of science and technology,andairborne guided weapons are becoming more and more digital and networked,which results in a increasing risk that airborne guided weapons can't perform satisfactorily in the complex electromagnetic environment.In this paper,the methods of the electromagnetic protection against the complex electromagnetic environment are analyzed.The main work of this paper are as follows:First,the researcheson electromagnetic protection against the complex electromagnetic environment for airborne guided weapons at home and abroardaresummarized.Combinedwith the technical and tactical characteristics of airborne guided weapons,the features and the functional principles of the complex electromagnetic environment that may be encountered by airborne guided weapons are concluded.Second,the influence pathways,functional principles and injurious effects of the complex electromagnetic environment areanalyzed,and the electromagneticprotection strategy for airborne guided weapons is proposed.At last,two examples that include an electromagnetic sensitivity component and an optical detection component are illustrated,and corresponding electromagnetic protection strategies are given.Based on the simulated results and measured results of experiments,an excellent electromagnetic suppression effect is obtained,which verifies the effectivity of the electromagnetic protection strategy in engineering applications.
