What are the main techniques used in Electronic Warfare (EW)?

• A. Electronic Attack (EA), Electronic Protection (EP), Electronic Support (ES)
• B. Jamming, Encryption, Hacking
• C. Radar, Sonar, Lidar
• D. Thermal imaging, Night vision, IR camera

Answer: (A)

Electronic Warfare is organized around three main techniques: Electronic Attack, Electronic Protection, and Electronic Support. Electronic Attack aims to disrupt or deny an adversary’s use of the electromagnetic spectrum, so activities like jamming, spoofing, and other deception methods fall under this umbrella. Electronic Protection focuses on keeping friendly systems effective in the face of such interference, using measures like hardening, anti-jamming techniques, frequency agility, and signal processing improvements to maintain operations. Electronic Support provides the intelligence side, detecting, analyzing, and locating emitters to understand the electromagnetic environment and support decision-making and targeting.

The other options mix in items that aren’t these three EW categories. Jamming is a technique within Electronic Attack but encryption and hacking belong to information security or cyber operations, not the EW framework. Radar, sonar, and lidar are sensing and navigation tools rather than the EW technique group, and thermal imaging, night vision, and IR cameras are imaging sensors, not EW techniques.
