radarszrdés

Radarszredés, commonly known as radar interference or radar jamming, refers to the deliberate or unintentional disruption of radar systems by emitting electromagnetic signals that interfere with their normal operation. This technique is primarily used in military contexts to deceive or blind enemy radar systems, thereby reducing their effectiveness in detecting and tracking targets such as aircraft, ships, or missiles.

The term originates from Hungarian, where *radar* and *szredés* (meaning "disturbance" or "interference") combine to describe the action. While radar jamming is often associated with warfare, it can also occur accidentally due to electronic interference from other sources, such as radio transmitters or industrial equipment. Modern radar systems employ various countermeasures, including frequency hopping, spread spectrum techniques, and advanced signal processing, to mitigate the effects of jamming.

Radar jamming can be categorized into three main types: passive, active, and repeat-forward jamming. Passive jamming involves emitting signals that mimic friendly radar returns, confusing enemy systems into detecting false targets. Active jamming directly interferes with the radar’s frequency, overwhelming its receiver with noise or false signals. Repeat-forward jamming captures and retransmits enemy radar signals, creating decoys or misleading the system about the target’s location.

In military applications, radar jamming is a critical component of electronic warfare (EW), enabling forces to evade detection and disrupt enemy operations. However, it also poses challenges for friendly forces, as unintended jamming can disrupt their own radar systems. Advances in technology, such as stealth aircraft and advanced radar stealth techniques, have made radar jamming less effective in some scenarios, prompting further innovation in both jamming and counter-jamming methods.
