Electronic warfare is any action that involves the use of the electromagnetic spectrum or directed energy to control the spectrum, attack an enemy or prevent enemy attacks across the spectrum.
The purpose of electronic warfare is to deny the opponent the advantage of, and ensure friendly and unhindered access to, the electromagnetic spectrum.
EW can be applied from the air, sea, land and space through manned and unmanned systems, and can be directed to humans, communications, radars or other assets.
The electromagnetic environment
Military operations are executed in an information environment increasingly complicated by the electromagnetic spectrum.
The portion of the electromagnetic spectrum of the information environment is known as the electromagnetic environment. The recognized need for military forces to have unimpeded access and use of the electromagnetic environment creates vulnerabilities and opportunities for electronic warfare in support of military operations.
Within the construct of information operations, EW is an element of information warfare; more specifically, it is an offensive and defensive counter-information element.
NATO has a different and more encompassing and comprehensive approach to early warning. A conceptual document of the Military Committee of 2007 recognized the EME as a space for operational maneuver and an environment / war domain. In NATO, EW is considered a war in the EME. NATO has adopted a simplified language that is parallel to those used in other war environments such as maritime, land and air / space.
For example, Electronic Attack is an offensive use of EM energy. ED is electronic defense and electronic surveillance ES. The use of traditional NATO EW measures has been preserved as they contribute and are compatible with EA, ED and ES. In addition to EW, other EM operations include ISTAR and SIGINT. Subsequently, NATO has issued the EW Policy and Doctrine and addresses the other NATO defense development lines.
Electronic warfare engineering
Electronic warfare is any military action that involves the use of the EM spectrum to include directed energy to control the electromagnetic spectrum or to attack an enemy. This is not limited to radio or radar frequencies, but includes IR, visible, ultraviolet and other less used portions of the electromagnetic spectrum. This includes self-protection, separation, escort blocking and anti-radiation attacks. EW is a specialized tool that improves many aerial and spatial functions at multiple levels of conflict.
The objective of EW is to deny the opponent an advantage in the MS spectrum and to guarantee friendly and unimpeded access to the EM spectrum part of the information environment. EW can be applied from the air, sea, land and space through manned and unmanned systems. EW is used to support military operations involving several levels of detection, denial, deception, interruption, degradation, protection and destruction.
