Quick Summary

Noise jamming is a form of electronic warfare used to degrade the effectiveness of military radar systems. It involves broadcasting a strong signal that overrides or obscures the target signal. This jamming signal enters the radar receiver via the antenna, increasing the noise level and making it difficult for the radar to detect actual target echoes. The goal is to confuse the radar, potentially causing it to display false targets or miss real ones. Military radar engineers develop countermeasures, known as electronic counter-countermeasures (ECCM), to combat jamming, often by quickly switching frequency channels.1234
