What is the purpose of Electronic Protection in electronic warfare?

• A. To degrade enemy sensors and communications.
• B. To safeguard friendly systems from jamming and interference.
• C. To gather spectrum information and intelligence.
• D. To perform reconnaissance on the opponent.

Answer: (B)

Electronic Protection is the defensive side of electronic warfare, focused on keeping friendly systems usable in a contested electromagnetic environment. Its purpose is to safeguard communications and sensors from jamming and interference by detecting disruption and applying mitigations—like anti-jam techniques, frequency agility, robust modulation and coding, filtering, shielding, and diverse antennas—to maintain reliable operation. This contrasts with attempts to degrade or deny enemy capabilities (electronic attack) or to collect spectrum information (electronic support) or perform reconnaissance. So the goal is to protect and preserve friendly systems in the face of jamming and interference.
