Noise jamming is defined as what?

Noise jamming is defined as what?

• A. A continuous signal radiated to conceal target return; can burn through; three categories spot, barrage, sweep
• B. A short pulse that disrupts communications
• C. A passive radar absorber
• D. A decoy chaff system

Answer: (A)

Noise jamming is the deliberate emission of a continuous, noise-like signal designed to conceal the radar target by flooding the receiver and raising the noise floor so the genuine target echo is masked. This is why the best description calls for a continuous signal radiated to conceal the target return, with the three forms—spot, barrage, and sweep—covering different ways to apply that energy across the spectrum: spot jams a single frequency, barrage spreads energy over a wide band, and sweep moves the jam across frequencies over time. This approach contrasts with short-pulse interference, which targets communications or specific timing, a passive radar absorber that simply absorbs energy, or chaff that creates false targets rather than masking the actual return.
