electromagnetic interference
Any electromagnetic disturbance, induced intentionally or unintentionally, that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics and electrical equipment
electromagnetic intrusion
The intentional insertion of electromagnetic energy into transmission paths in any manner, with the objective of deceiving operators or of causing confusion
electromagnetic jamming
The deliberate radiation, reradiation, or reflection of electromagnetic energy for the purpose of preventing or reducing an enemy’s effective use of the electromagnetic spectrum, and with the intent of degrading or neutralizing the enemy’s combat capability
electromagnetic operational environment
The background electromagnetic environment and the friendly, neutral, and adversarial electromagnetic order of battle within the electromagnetic area of influence associated with a given operational area
electromagnetic pulse
The electromagnetic radiation from a strong electronic pulse, most commonly caused by a nuclear explosion that may couple with electrical or electronic systems to produce damaging current and voltage surges
electromagnetic radiation
Radiation made up of oscillating electric and magnetic fields and propagated with the speed of light
electromagnetic radiation hazards
Transmitter or antenna installation that generates or increases electromagnetic radiation in the vicinity of ordnance, personnel, or fueling operations in excess of established safe levels
electromagnetic spectrum
The range of frequencies of electromagnetic radiation from zero to infinity. It is divided into 26 alphabetically designated bands
electromagnetic spectrum control
The coordinated execution of joint electromagnetic spectrum operations with other lethal and nonlethal operations that enable freedom of action in the electromagnetic operational environment
electromagnetic spectrum management
Planning, coordinating, and managing use of the electromagnetic spectrum through operational, engineering, and administrative procedures
electromagnetic vulnerability
The characteristics of a system that cause it to suffer a definite degradation
(incapability to perform the designated mission)
as a result of having been subjected to a certain level of electromagnetic environmental effects
electronic attack
Division of electronic warfare involving the use of electromagnetic energy, directed energy, or antiradiation weapons to attack personnel, facilities, or equipment with the intent of degrading, neutralizing, or destroying enemy combat capability and is considered a form of fires
Electronic Compliance Assistance Tool
ECAT
Electronic Filing Interface
EFI
electronic intelligence
Technical and geolocation intelligence derived from foreign noncommunications electromagnetic radiations emanating from other than nuclear detonations or radioactive sources.
electronic masking
The controlled radiation of electromagnetic energy on friendly frequencies in a manner to protect the emissions of friendly communications and electronic systems against enemy electronic warfare support measures/signals intelligence without significantly degrading the operation of friendly systems
Electronic Numerical Integrator And Computer
ENIAC
electronic probing
Intentional radiation designed to be introduced into the devices or systems of potential enemies for the purpose of learning the functions and operational capabilities of the devices or systems
electronic protection
Division of electronic warfare involving actions taken to protect personnel, facilities, and equipment from any effects of friendly or enemy use of the electromagnetic spectrum that degrade, neutralize, or destroy friendly combat capability
electronic reconnaissance
The detection, location, identification, and evaluation of foreign electromagnetic radiations
