Electromagnetic pulse protection requirments and test methods for systems

Electromagnetic pulse (EMP) radiation may seriously threaten the electronic equipments and systems. The EMP energy could be coupled into inside of systems from antennas, cables and apertures, and this would result in the system disturbed even destroyed. The EMP coupling characteristics of different channels are analyzed in this paper, and the general protection requirements for different types of coupling path are investigated. Based on the electromagnetic compatibility (EMC) requirements and test methods for systems and subsystems, the EMP protection test methods combined with radiation and injection for systems are proposed in this paper.
