Which device is used to confuse radar?

• A. Electronic Countermeasures
• B. Chaff
• C. Infrared flares
• D. Radar

Answer: (A)

Confusing radar relies on methods that disrupt how radar perceives its environment. Electronic countermeasures are the set of tools and techniques designed to degrade radar performance, whether by flooding the receiver with noise, spoofing the returns, or creating false targets. This broad capability covers tactics like chaff, which releases metallic strips to generate a cloud of false echoes that obscure real aircraft. Infrared flares are aimed at infrared seekers, not radar, so they don’t confuse radar waves. The radar itself is the system being countered, not a countermeasure. So the best answer is electronic countermeasures, because it represents the overall approach used to disrupt and deceive radar operation.
