Which term refers to deception as a tactic within electronic countermeasures?

• A. Jamming
• B. Deception
• C. Neutralisation
• D. Encryption

Answer: (B)

Deception as an ECM tactic is about misleading the adversary by feeding them false information through their sensing and decision systems. The aim is to confuse targets, tracks, or guidance, making them act on incorrect data rather than just defeating the signal. Examples include spoofing radar returns with false targets or decoys, or providing counterfeit data that alters the perceived position, speed, or intent of a platform. This stands in contrast to jamming, which simply floods the receiver with interference to reduce readability; neutralisation, which seeks to disable or destroy equipment; and encryption, which protects one's own communications rather than deceiving the opponent. So deception is the term that best describes using misleading information as a tactic in electronic countermeasures.
