Electronic warfare (EW) is the use of the electromagnetic spectrum to effectively deny the use of this medium by an adversary, while optimizing its use by friendly forces. Electronic warfare has three main components: electronic support, electronic attack, and electronic protection.

[edit] Electronic support

Main article: Electronic support

Electronic Warfare Support (ES), in military terms, is the passive detection of signals in order to detect and locate threats or target location, information necessary to conduct Electronic Attack (EA). By comparison, Signals Intelligence (SIGINT) is the related process of analyzing and identifying the intercepted frequencies (e.g. as a cell phone or RADAR). SIGINT is a combination of ELINT, COMINT, and MASINT.

Government, law enforcement, and military operational techniques are governed by US Codes for use with intelligence gathering procedures.

[edit] Electronic attack

Main article: Electronic attack

Electronic attack (EA) is the active or passive use of the electromagnetic spectrum to deny its use by an adversary.

• Active EA includes such activities as jamming, deception, active cancellation, and EMP use.

• Passive EA includes such activities as the use of chaff, balloons, radar reflectors, Faraday cages, winged decoys, and stealth.

EA operations can be detected by an adversary due to their active transmissions. Many modern EA techniques are considered to be highly classified.

An older term for EA is electronic countermeasures (ECM).

[edit] Electronic protection

Main article: Electronic protection

Electronic protection (EP) includes all activities related to making enemy EA activities less successful by means of protecting friendly personnel, facilities, equipment or objectives. EP can also be implemented to prevent friendly forces from being affected by their own EA.

• Active EP includes such activities as technical modifications to radio equipment (such as frequency-hopping spread spectrum).

• Passive EP includes such activities as the education of operators (enforcing strict discipline) and modified battlefield tactics or operations.

Older terms for EP include electronic protective measures (EPM) and electronic counter countermeasures (ECCM).
