Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults.
The purpose of electronic warfare is to deny the opponent the advantage
Electronic Warfare (EW) represents the ability to use the electromagnetic spectrum—signals such as radio, infrared or radar—to sense, protect, and communicate. At the same time, it can be used to deny adversaries the ability to either disrupt or use these signals.
EW is divided into three (3) major areas:
- Electronic Attack: Disrupt, deny, degrade, destroy, or deceive
- Electronic Protection: Preventing a receiver from being jammed or deceived
- Electronic Support: Sensing of the electromagnetic spectrum
