What technique is used to manipulate the frequency and amplitude of noise signals in Electronic Jamming?

Noise Modulation involves the technique of manipulating the frequency and amplitude of noise signals to disrupt enemy communications or radar systems. By tailoring the noise in such a way, it can effectively mask or overpower the signals that an adversary is using. This process typically involves varying characteristics of the noise, such as its frequency and amplitude, in a way that can confuse or inhibit detection and response from the target system.

In electronic jamming, particularly against radar, changing the noise can optimize the jamming effect by ensuring that the signal remains unpredictable and difficult for the target to filter out. This adaptability is crucial for maintaining effective jamming over time, as it can counteract countermeasures employed by adversaries.

Other techniques like Frequency Hopping, Waveform Shaping, and Signal Marking might involve altering signal transmissions but do not primarily focus on the direct manipulation of noise signals specifically for jamming purposes. Therefore, the focus on manipulating noise through Noise Modulation is key to its effectiveness in jamming operations.
