Knowra Electronic warfare Electronic warfare Electronic warfare comprises military actions that use or counter electromagnetic energy to disrupt, deceive, or exploit an adversary, or to protect friendly forces.
Electronic attack : The use of electromagnetic energy or directed energy to degrade, neutralize, or destroy an adversary’s capabilities. This is the offensive function, including jamming and electromagnetic deception.
Electronic countermeasure : A device or tactic used to disrupt or deceive an adversary’s sensors or communications. Countermeasures translate electronic-attack aims into operational techniques.
Battle of Tsushima : The 1905 naval battle in which Japan defeated Russia in the Sea of Japan. Japanese radio interference during the battle is an early recorded example of disrupting military communications.
Cyberwarfare : Hostile activity that targets or exploits computer systems and networks for military or political purposes. Cyber operations target digital systems, while electronic warfare contests electromagnetic energy and signals.
Radar stealth : Techniques that reduce an object’s detectability by radar through shaping, materials, and design. The threat of radar detection and electronic attack influences efforts to reduce radar signatures.
Electronic protection : Measures that protect personnel, equipment, and operations from the effects of friendly or adversary electromagnetic energy. It preserves friendly systems against jamming, interference, and other electromagnetic threats.
Chaff (countermeasure) : Clouds of radar-reflective fibers released to create false radar targets or obscure an aircraft. Chaff is a defensive countermeasure that complicates radar tracking.
World War II radar : The wartime development and use of radar for detection, navigation, and air defense. Radar’s military value drove rapid advances in jamming, interception, and countermeasures.
Information warfare : The use and protection of information to influence, disrupt, or gain advantage over an adversary. Electronic warfare is one way military forces can affect information flows and decision-making.
Emission control : Procedures that limit or manage electromagnetic transmissions to reduce detection or interference. Forces may restrict emissions to avoid revealing positions or inviting electronic attack.
