Electromagnetic Environment Effects and Protection of Complex Electronic Information Systems

With the development of science and technology and military strategy, the equipment platform will widely adopt new technologies such as stealth, radio frequency integration, integrated superstructure, as well as new system information systems and directed energy technology applications, etc., to meet the platform performance and system combat capabilities. The complex equipment platform will face the electromagnetic environment adaptability problem caused by the electromagnetic environment such as the platform, the formation system, the battlefield strong electromagnetic pulse environment. In particular, the strong electromagnetic pulse environment belongs to a high-power electromagnetic environment, and its energy is very large, which will pose a serious threat to modern information systems. To this end, this paper addresses the challenges faced by electronic information systems in dealing with the effects of electromagnetic environment, expounds the connotation of complex electromagnetic environment, analyzes the coupling mechanism of strong electromagnetic pulse environment and electronic information system, and explores the multi-physics damage mechanism of sensitive parts of electronic information system , Introduces the current commonly used electromagnetic protection and new electromagnetic protection methods, and puts forward suggestions for electromagnetic protection.
