Which statement best characterizes barrage jamming?

• A. Jamming multiple target signals using a wideband waveform
• B. Spot jamming on a single frequency
• C. Hopped/swept jamming
• D. Coherent jamming

Answer: (A)

Barrage jamming works by filling a wide portion of the spectrum with noise-like energy so many channels are affected at once. The idea is to overwhelm receivers across a broad bandwidth, degrading or destroying the ability to demodulate any of the signals within that range. This is in contrast to spot jamming, which targets a single frequency, hopped/swept jamming that changes frequency to avoid fixed filters, or coherent jamming that tries to cancel a specific signal with a synchronized jamming signal. So the statement that best characterizes barrage jamming is that it jams multiple target signals using a wideband waveform.
