THEORETICAL CONSIDERATIONS REGARDING ASSESSMENT OF HEMP AND IEMI UPSET OF DIGITAL SYSTEMS

This paper discusses the major analytical techniques and processes for assessing the response and upset of complex digital systems to the high-altitude electromagnetic pulse (HEMP) and to wideband pulsed Intentional Electromagnetic Interference (IEMI). We focus on electronic or communication information systems in a building containing computer network(s) with power cables and interconnecting data cables. External power and data cables enter the interior region that contains the system as well. The digital systems are considered to have a unit subsystem of a pair of electronic systems that store and process information connected by some communications channel such as a data bus
