How does deception/repeater jamming differ from noise jamming?

• A. It manipulates received radar energy and retransmits it as false targets
• B. It increases target reflectivity
• C. It reduces transmitter power
• D. It uses mechanical decoys

Answer: (A)

Deception/repeater jamming works by turning the radar’s own energy against it to create false targets. It picks up the received radar pulses and retransmits them with timing, phase, or power adjustments so the radar sees spoof returns at believable ranges or speeds, effectively misleading the operator. This is different from noise jamming, which simply floods the receiver with random signals to raise the noise floor and degrade detection without creating fake targets. The other options don’t fit because increasing target reflectivity isn’t something the jammer controls, reducing transmitter power isn’t how deception works, and using mechanical decoys is a separate tactic that doesn’t involve manipulating the received radar energy to generate spoofed returns.
