The fundamental purpose of jamming is often to block, distort, or manipulate signals in a way that inhibits information transfer.

Signal jamming works based on several principles:

Frequency Interference: Jamming devices transmit signals that disrupt the intended communication frequency. When two signals occupy the same frequency, they interfere with each other, making it difficult for the receiver to detect the legitimate signal.
Noise Generation: Jammers can generate noise over a wide frequency range, creating a blanket of interference that makes it hard for devices to communicate effectively. This noise effectively masks legitimate signals.
Power Level Manipulation: By adjusting the power levels of the jamming signal, it’s possible to overpower the legitimate signal, ensuring that the jamming signal dominates.
Pulse Width Modulation: Some jammers use pulse-width modulation techniques to create bursts of jamming signals that disrupt communication during specific time frames.
Adaptive Techniques: Advanced jammers can detect the signals they are targeting and adjust their output accordingly to maximize disruption.
Continuous vs. Intermittent Jamming: Jamming can be continuous, where signals are constantly transmitted, or intermittent, where signals are sent in bursts. Intermittent jamming can be harder to detect and can catch systems off guard.
Frequency Hopping: Some jammers utilize frequency-hopping techniques, where they quickly switch frequencies to evade detection and maintain interference across various communication channels.
Directionality: Certain jamming devices can focus their interference in specific directions, allowing them to jam signals targeted at a particular location while minimizing the impact on other areas.
