Which statement correctly differentiates barrage jamming from spot jamming?

• A. Barrage jamming uses a wideband signal to jam multiple targets, whereas spot jamming targets a single frequency
• B. Barrage jamming targets a single frequency; spot jamming uses a wideband signal
• C. Spot jamming uses a wideband signal to jam multiple targets
• D. Barrage jamming relies on coherent data streams

Answer: (A)

The distinction being tested is how the jammer distributes energy across the spectrum. Barrage jamming spreads energy over a wide portion of the spectrum, aiming to disrupt many frequencies at once and interfere with multiple channels or links. Spot jamming concentrates power on a single frequency (or a very narrow band), overwhelming the receiver on that particular channel while leaving others relatively unaffected. Because barrage is wideband and targets multiple frequencies, while spot jamming is narrowband and targets one frequency, the statement describing barrage as wideband and able to jam multiple targets, with spot jamming focusing on a single frequency, is the best description. Coherence of data streams isn’t the defining factor here; the key difference is bandwidth distribution and the scope of interference.
