1 Scope
This part of the Electromagnetic Compatibility Environment defines a high altitude electromagnetic pulse (HEMP) environment, one of the effects of high altitude nuclear explosions.
There are two situations to consider when studying this topic.
---High altitude nuclear explosion;
--- Low-altitude nuclear explosion.
For civilian systems, the most serious situation is a high-altitude nuclear explosion. In this case, other effects of nuclear explosions, such as explosions,
Ground impact, heat radiation and ionizing radiation will not affect the ground. However, electromagnetic pulses generated by nuclear explosions may cause communication systems.
Damage and destruction of the system, electronics and power systems, which in turn affects the stability of modern society.
The purpose of this section is to establish a general reference for the HEMP environment, to select the actual environmental parameters for sensitive devices, and to evaluate their sensitivity.
Sensitivity.

3 Overview
High-altitude (above 30km) nuclear explosions produce three types of electromagnetic pulses that can be observed on the Earth's surface.
--- Early high altitude electromagnetic pulse (fast);
--- Medium-term high altitude electromagnetic pulse (medium);
--- Late high altitude electromagnetic pulse (slow).
Historically, most of the attention has been focused on early high-altitude electromagnetic pulses, which once briefly recognized high-altitude electromagnetic pulses.
It means the early high-altitude electromagnetic pulse. And here, the term "high altitude EMP" or "HEMP" we use will include all three types of electricity.
Magnetic pulse. The term nuclear electromagnetic pulse (NEMP1) covers many categories, including nuclear electromagnetic pulses in the source region generated by ground nuclear explosions.
(SREMP2)) and system electromagnetic pulse (SGEMP3) excited in the space system.
Since high-altitude electromagnetic pulses (HEMP) are generated by high-altitude nuclear explosions, there will be no other nuclear weapons effects on the ground, such as gamma rays, heat.
Radiation, shock waves, etc. In the early 1960s, the United States conducted high-altitude nuclear explosion tests in the South Pacific, resulting in electronic settings far from the explosion point.
For the first time in the report of the huge effect, the term high-altitude electromagnetic pulse (HEMP) appeared.
1) NEMP. Nuclear electromagnetic pulse.
2) SREMP. Nuclear electromagnetic pulse in the source area.
3) SGEMP. System electromagnetic pulse.
