Which of the following lists are types of electronic deception jammers?

• A. Repeater-Jammers, Range-Gate Stealers, Velocity-Gate Stealers
• B. Noise Jammers, Chaff, Flares
• C. Infrared Jammers, Sonobuoys, Visual Decoys
• D. Chaff, Flares, Sonobuoys

Answer: (A)

Electronic deception jammers deliberately manipulate the radar signal to mislead the radar about where a target is or how fast it is moving. The standout types are repeater-jammers, which take the radar’s own signal and retransmit it with modifications to create false readings; range-gate stealers, which inject forged returns to confuse the radar’s distance measurement; and velocity-gate stealers, which spoof the Doppler information to distort the target’s perceived speed. The other items don’t fit this category: noise jammers simply flood the receiver with random noise rather than feed back false data; chaff and flares are physical decoys, not electronic deception of the radar signal itself; infrared jammers, sonobuoys, and visual decoys target other domains or subsystems and aren’t RF deception jammers. So the list that includes repeater-jammers, range-gate stealers, and velocity-gate stealers is the one that identifies electronic deception jammers.
