What are the three major categories of noise jamming?

• A. Spot, barrage, and sweep
• B. Pulse, continuous, and modulated
• C. Sweep, scatter, and pulse
• D. Line, beam, and envelope

Answer: (A)

Noise jamming is categorized by how the jammer distributes its energy across the spectrum to disrupt radar. The three main types are spot jamming, barrage jamming, and sweep jamming. Spot jamming concentrates power on a single frequency or Doppler bin, overwhelming the radar’s return at that precise point. Barrage jamming dumps energy across a wide portion of the band at once, raising the noise floor and degrading reception over many channels. Sweep jamming shifts the jammer’s noise across frequencies in time, so as the radar sweeps its own frequency, the jamming tracks along and remains effective. The other groupings don’t reflect this typical classification, as they refer to different signal traits rather than how noise jamming is applied.
