1 Scope and purpose

This section GB/T 18039 requirements of high-altitude nuclear electromagnetic pulse (HEMP) conducted environment, HEMP series of high-altitude nuclear explosion effect it should be one of the research topics such two cases to consider.

--- High-altitude nuclear explosion;

--- Low-altitude nuclear explosions.

The civil system, the two cases are among the most important high-altitude nuclear explosions. High-altitude nuclear explosion is characterized by a shock wave, the earth shook, Thermal radiation and nuclear radiation and other effects of nuclear explosions on the ground does not exist, but the electromagnetic pulse generated by a nuclear explosion would cause communication, electricity Son and electrical systems work interruptions and damage, disrupting the stability of modern society.

The purpose of this section is to establish a common standard on HEMP environment, in order to determine the true from electromagnetic disturbance environment for Evaluate the performance of the device by the impact.

30km above the ground from the electromagnetic pulse generated by high-altitude nuclear explosion, there is observed on the surface of the Earth in three types.

--- Early HEMP (fast);

--- Mid-HEMP (middle);

--- Late HEMP (slow).

In the past, people focus on early HEMP, referred to simply as "HEMP". As used in this section, but "high-altitude EMP" the term or "HEMP", including the above three types of nuclear electromagnetic pulse (NEMP) The term covers a variety of nuclear electromagnetic pulse, including Ground source region explosion electromagnetic pulse (SREMP-SourceRegionEMP) and system electromagnetic pulse (SGEMP- space generated SystemGeneratedEMP).
