What is spot jamming?

What is spot jamming?

• A. Single target signal on one frequency
• B. Jamming multiple target signals using a wideband waveform
• C. Using a narrowband waveform to sweep across multiple target signals
• D. Modulation of incoherent to random pattern of bits that does not contain data

Answer: (A)

Spot jamming is targeted interference that concentrates all jammer power on a single carrier to disrupt one channel. By transmitting a strong signal on the exact frequency of the desired signal, the receiver’s ability to recover the original data is severely degraded, making demodulation extremely difficult. This approach is efficient because it wastes minimal power while taking down just one link, rather than flooding a broad portion of the spectrum. It’s different from wideband or barrage jamming, which covers many frequencies at once, and from sweeping methods that move a narrow interference across frequencies over time. The description that talks about a random, noise-like pattern not carrying data doesn’t match the focused, single-frequency nature of spot jamming.
