RF Jammer
An RF jammer is a device that intentionally transmits radio signals to block or interfere with communications. It's used to disrupt enemy radios, disable remotely-controlled weapons like drones, or prevent the detonation of improvised explosive devices (IEDs).
TECHNICAL DEFINITION
An RF (Radio Frequency) jammer is an electronic warfare (EW) device that generates and transmits electromagnetic energy to create intentional interference, disrupting or denying an adversary's use of the electromagnetic spectrum. This electronic countermeasure (ECM) targets command and control (C2) links, datalinks for unmanned systems (UAS), and triggers for remote-controlled improvised explosive devices (RCIEDs), serving as a critical component in force protection and Counter-UAS (C-UAS) systems.
BACKGROUND
Radar jamming and deception is a form of electronic countermeasures (ECMs) that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while systems that produce confusing or contradictory signals are known as deception, but it is also common for all such systems to be referred to as jamming.

USAGE NOTE
Jammers are deployed to create a protective electromagnetic bubble, but their use must be carefully managed to avoid interfering with friendly communications systems.
