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 ...
A laser jammer or lidar jammer is an electronic device used by drivers to prevent users of a LIDAR (or laser) gun from obtaining speed readings of their vehicle. Laser jammers are not to be confused with radar jammers. To jam LIDAR, laser jammers first must detect the emitted light, normally infrared light on the 904 nm wavelength. [12]
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real ...
A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding. In general sense, only emitting technologies, like doppler RADAR, or LIDAR can be detected.
There's no nationwide standard for police radar; an officer in rural Nebraska may still use 30-year-old X-band guns (don't ask us how we know), while urban police use Ka-band radar or even laser guns.
Digital radio frequency memory. Digital Radio Frequency Memory (DRFM) is an electronic method for digitally capturing and retransmitting RF signals. DRFM systems are typically used in radar jamming, although applications in cellular communications are becoming more common.

Radio jamming. Radio jamming is the deliberate blocking of or interference with wireless communications. [1][2] In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio. [3]
