Abstract

Gives the high-altitude electromagnetic pulse (HEMP) environment that is one of the consequences of a high-altitude nuclear explosion. Two cases are considered: a) high-altitude nuclear explosions; b) low-altitude nuclear explosions. The most important case is the high-altitude nuclear explosion. The other effects of the nuclear explosion: ground shock, thermal and nuclear ionizing radiation, blast, in this case are not present at ground level. The aim of this is to establish a common reference for the HEMP environment so as to select realistic stresses applicable to victim equipment to evaluate their performance.
