Which statement best describes hopping or swept jamming?

• A. Hopped/swept jamming uses a narrowband waveform to sweep across multiple targets
• B. Hopped/swept jamming spreads a signal over a wide bandwidth
• C. Hopped/swept jamming jams a single frequency with a fixed tone
• D. Hopped/swept jamming uses incoherent random bits to jam the channel

Answer: (A)

Hopping or swept jamming works by moving the jam across frequencies so it disrupts multiple channels rather than staying on one spot. The description that fits this best is using a narrowband jammer and sweeping it across several frequencies. By switching or sweeping the jammer’s frequency, you can affect multiple targets or channels in turn, which is the essence of hopping/swept jamming. If the jammer were to spread its power over a wide band, that would be wideband or barrage jamming, not hopping or swept. If it stayed on a single fixed frequency with a tone, it would only disrupt one channel. If it relied on random, noise-like bits, that would be a noise-type jam rather than a deliberate frequency move across the spectrum.
