Electronic warfare, also known as electronic attack, is the use of military power and technological infrastructure to prevent enemy forces from using the electromagnetic spectrum, including radio waves and radar frequency bands. This disruption aims to reduce or disrupt their capabilities in navigation, target detection, tracking, telecommunications, and intelligence sharing, thereby hindering electronic communication among the links forming the command chain. Electronic attack can be executed actively or passively. 

Active electronic attack involves activities such as jamming enemy radio communications by emitting parasitic radio waves at high power levels, conducting electronic or human disinformation campaigns in the same frequency band, deceiving enemy radio/intelligence operators or radar receivers, transponder stations, and using active wave cancellation techniques and electromagnetic pulse (EMP) bombs, which have become common, especially in aircraft. 

In addition to these methods, the term "digital attack" has emerged in recent years, especially with the widespread use of the Internet. With military command centers and databases becoming accessible via the Internet, this concept has begun to be categorized as active electronic attack due to its potential to be exploited by skilled computer hackers and aggressors. Passive electronic attack includes measures such as shafts left behind to deceive radar on combat aircraft, radar reflectors, Faraday cages, winged decoys, or deceivers, as well as stealth technologies. 

Passive electronic attacks do not generate any electromagnetic pollution by their nature, making them less easily detectable by enemy sensors. In some cases, this can be an advantage over active electronic attacks, which can be detected much earlier. Many details about electronic attack methods are classified as military or state secrets.
