A jammer is a type of electronic warfare system designed to operate at a distance from the target it intends to jam. It typically uses powerful transmitters and sophisticated signal processing capabilities to disrupt enemy radar, communications, or other electronic systems from a safe distance. Stand-off fogs are often deployed on aircraft or unmanned vehicles to protect friendly forces by denying the adversary the ability to detect or communicate effectively.
A jammer, on the other hand, is an electronic warfare system that operates closer to the target it intends to disrupt.
Unlike fogs, which operate at a distance, fogs can infiltrate enemy territory or operate within the engagement range of the adversary’s electronic systems. This proximity allows fogs to make enemy radar, communications, or other electronic signals with precision and intensity.
The three main types of jamming techniques are jamming, deception jamming, and barrage jamming. Noise jamming involves flooding the communications channel or radar band with an overwhelming amount of random electromagnetic energy, disrupting the signal.
Deception jamming works by emitting signals that imitate legitimate radar outputs or communications, confusing enemy electronic systems. Barrier jamming uses a wideband signal to block all frequencies in a specific band, preventing targeted communication or radar operation.
There are several types of fogs classified by their intended targets and operational environments. Common types include radar fogs, which disrupt radar signals; Jamming communications, which interfere with enemy communications; and GPS jammers, which disrupt global positioning system signals.
Each type of jammer is designed to disrupt specific electronic systems critical to adversary operations.
A self-protection jammer is a defensive electronic warfare system designed to protect a platform (such as an aircraft or ground vehicle) from incoming threats by jamming or deceiving targeting or guidance systems. These jammers are typically compact, highly specialized systems that can quickly detect and respond to threats such as radar-guided missiles or ground targeting systems, improving the survivability of the protected platform in combat situations
