Electromagnetic pulse weapon is a weapon system that uses strong electromagnetic pulse radiation to destroy the enemy's radar, communication, computer, power and other electromagnetic related equipment, so as to seize the advantage of the battlefield. EMP weapons are mainly used to deal with the enemy's electronic information system.
Electromagnetic pulse weapons can be divided into strategic electromagnetic pulse weapons and tactical electromagnetic pulse weapons according to the scope of operation and power. Strategic electromagnetic pulse weapon is also called nuclear electromagnetic pulse weapon. It is made according to the electromagnetic pulse effect of nuclear explosion. When the nuclear bomb explodes, it is powerful and releases strong γ Ray. γ Because of its high energy, the ray can ionize the air, and the ionized electrons leave the explosion center at the speed of light. In this way, a large number of positive ions gather around the explosion center, forming a very strong electromagnetic field.
The electromagnetic field radiates outward under asymmetric conditions, so nuclear electromagnetic pulse is generated. The characteristics of nuclear electromagnetic pulse are: short duration and high electromagnetic field intensity; Wide frequency range; The action range is large, up to several kilometers; Fast propagation speed; It only poses a threat to electronic equipment. Tactical electromagnetic pulse weapon is made by using the principles of laser effect, charged particle effect and pulse radioactivity.
