Which description best defines Repeater-Jammers?

• A. Receive, analyze, amplify, and remodulate received signals, and transmit them on the enemy's frequency with false information
• B. Introduce a time delay into the return energy
• C. Deny radar scan
• D. Simply jam communications

Answer: (A)

Repeater-jammers are deception tools in electronic warfare. They intercept an incoming signal, analyze its content, amplify and remodulate it, and then transmit a counterfeit version on the enemy’s frequency containing false information. The goal is to mislead the adversary by presenting credible but incorrect data, effectively turning their own signals against them. This exact sequence—receive, analyze, remodulate, and retransmit with deception—best defines a repeater-jammer. Other approaches describe different techniques: introducing a time delay would affect timing for range deception but doesn’t involve sending a false signal; denying radar scan is a blocking tactic, not spoofing; simply jamming communications disrupts channels without fabricating believable information.
