An electromagnetic pulse (EMP), also referred to as a transient electromagnetic disturbance (TED), is a brief burst of electromagnetic energy. The origin of an EMP can be natural or artificial, and can occur as an electromagnetic field , as an electric field , as a magnetic field , or as a conducted electric current .
A nuclear electromagnetic pulse (nuclear EMP or NEMP) is a burst of electromagnetic radiation created by a nuclear explosion.The resulting rapidly varying electric and magnetic fields may couple with electrical and electronic systems to produce damaging current and voltage surges.
An electromagnetic pulse (EMP), sometimes called a transient disturbance, is a short-duration pulse of energy. This energy is usually broadband by nature, although it often excites a relatively narrow-band damped sine wave response in the victim. Pulse signals divide broadly into isolated and repetitive events.
These MeV-energy Compton electrons then accelerate and spiral along the Earth's magnetic field lines. The resulting transient electric fields and currents generate electromagnetic emissions in the radio frequency range of 15 MHz to 250 MHz. This high-altitude EMP occurs between 30 and 50 kilometers (19 and 31 miles) above the Earth's surface.
The Counter-electronics High Power Microwave Advanced Missile Project (CHAMP) is a joint concept technology demonstration led by the Air Force Research Laboratory, Directed Energy Directorate at Kirtland Air Force Base to develop an air-launched directed-energy weapon capable of incapacitating or damaging electronic systems [55] by means of an ...
A variant of this is the high altitude EMP (HEMP) nuclear weapon, designed to create the pulse as its primary destructive effect. Non-nuclear electromagnetic pulse (NNEMP) weapons. Sources of repetitive EMP events, sometimes as regular pulse trains, include: Electric motors; Electrical ignition systems, such as in gasoline engines.
Nuclear and large conventional explosions produce radio frequency energy. The characteristics of the EMP will vary with altitude and burst size. EMP-like effects are not always from open-air or space explosions; there has been work with controlled explosions for generating electrical pulse to drive lasers and railguns.
Analysis showed that low-frequency (150-190 kilohertz) radio transmissions were largely unaffected by high-altitude EMP, and the Air Force Weapons Laboratory (Kirtland Air Force Base) tested a small scale 'groundwave' transmission system in 1978-1982. Based on the groundwave concept's promise, USAF Headquarters issued a draft Program Management ...
