  2. Radar jamming and deception - Wikipedia

    en.wikipedia.org/wiki/Radar_jamming_and_deception

    Mechanical jamming devices include chaff, corner reflectors, and decoys. Chaff is made of different length metallic strips, which reflect different frequencies, to create a large area of false returns in which a real contact would be difficult to detect. Modern chaff is usually aluminum-coated glass fibers of various lengths.

  3. Chaff (countermeasure) - Wikipedia

    en.wikipedia.org/wiki/Chaff_(countermeasure)

    The RR-144 is designed to prevent interference with civil ATC radar systems. Chaff, originally called Window [1] or Düppel, is a radar countermeasure involving the dispersal of thin strips of aluminium, metallized glass fiber, or plastic. [2] Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. [3]

  4. Radar detector - Wikipedia

    en.wikipedia.org/wiki/Radar_detector

    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 .

  5. Pulse-Doppler signal processing - Wikipedia

    en.wikipedia.org/wiki/Pulse-Doppler_signal...

    Valid reflectors produce a lock. Invalid signals do not. Invalid reflections include things like helicopter blades, where Doppler does not correspond with the velocity that the vehicle is moving through the air. Invalid signals include microwaves made by sources separate from the transmitter, such as radar jamming and deception.

  6. Boomerang (countermeasure) - Wikipedia

    en.wikipedia.org/wiki/Boomerang_(countermeasure)

    The Boomerang unit attaches on a mast to the rear of a vehicle and uses an array of seven small microphone sensors. The sensors detect and measure both the muzzle blast and the supersonic shock wave from a supersonic bullet traveling through the air (and so is less effective against subsonic ammunition).

  8. Radar tracker - Wikipedia

    en.wikipedia.org/wiki/Radar_tracker

    A radar tracker is a component of a radar system, or an associated command and control (C2) system, that associates consecutive radar observations of the same target into tracks. It is particularly useful when the radar system is reporting data from several different targets or when it is necessary to combine the data from several different ...

    The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.
