Communication system IEMI vulnerability evaluation system and evaluation method

Abstract

The invention relates to a communication system IEMI vulnerability evaluation system and evaluation method, and aims to solve the problems that an electromagnetic environment and a use scene close to a real environment cannot be simulated in a test environment in the existing research for evaluating the influence of an electromagnetic pulse on the performance of a communication system. Due to the high integration of actual equipment, an electromagnetic pulse conduction coupling mechanism and communication performance index fine measurement cannot be further researched. The system comprises a communication system, an IEMI environment library, a traditional communication interference waveform library, a channel model library, a simulation environment parameter control module and an effect index evaluation and analysis module; the communication system comprises short-wave communication, ultra-short-wave communication, meteoric trail communication and covered wire communication; each communication is composed of a transmitter and a receiver, and each of the transmitter and the receiver is composed of a baseband signal processing unit and a radio frequency channel model library. The evaluation method comprises coupling conduction analysis of IEMI electromagnetic interference and/or evaluation of influence of key vulnerable components on performance degradation of the communication system.

Description

technical field [0001] The invention relates to a communication system IEMI vulnerability evaluation system and evaluation method, which are specifically applied to performance degradation evaluation of a communication system in a malicious electromagnetic interference (Intentional Electromagnetic Interference, IEMI) environment. Background technique [0002] With the rapid development of modern electronic technology, wireless communication systems will be attacked by various malicious electronic interference (IEMI), such as high-power microwave (HPM), ultra-wideband electromagnetic pulse (UWB-EMPs), high-altitude electromagnetic pulse (HEMP), etc. (See GIRID V, HOAD R, SABATH F. High-power electromagnetic effects on electronic systems[M]. LONDON: ARTECH HOUSE, 2020:20-30). When the communication system is attacked by IEMI, the effect phenomena mainly include hard failure (system failure cannot communicate), soft effect (recoverable after restarting) and permanent performanc...
