What EA technique uses noise jamming output related to the scan rate of tracking RADAR?

The technique that employs noise jamming output related to the scan rate of tracking radar is amplitude modulated noise. This method is designed to effectively mask the radar signals by introducing noise that is synchronized with the radar's scanning behavior. By modulating the amplitude of the noise in relation to the radar's scanning, the jamming signal can create interference at the specific frequencies and timing patterns that the radar is using, thereby degrading the radar's ability to accurately track or lock onto its intended target.

This synchronization is crucial because it maximally impacts the radar’s performance, which typically relies on persistent returns from targets. When the jamming noise matches the radar's scan rate, it can effectively obscure the target’s return signals, making it difficult, if not impossible, for the radar operator to distinguish between legitimate signals and the jamming noise. This technique is particularly useful in scenarios where the radar is continuously scanning for threats, as it can disrupt the tracking capabilities without requiring complex signal processing on the part of the jammer.
