  2. Luneburg lens - Wikipedia

    en.wikipedia.org/wiki/Luneburg_lens

    Removable Luneburg lens type radar reflectors are sometimes attached to military aircraft in order to make stealth aircraft visible during training operations, or to conceal their true radar signature. Unlike other types of radar reflectors, their shape doesn't affect the handling of the aircraft. [9] [10]

  3. Corner reflector - Wikipedia

    en.wikipedia.org/wiki/Corner_reflector

    A corner reflector for radar testing. A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat reflective surfaces. It reflects waves incident from any direction directly towards the source, but translated.

  4. Radar jamming and deception - Wikipedia

    en.wikipedia.org/wiki/Radar_jamming_and_deception

    Corner reflectors are many-sided objects that re-radiate radar energy mostly back toward its source. An aircraft cannot carry as many corner reflectors as it can chaff. Decoys are maneuverable flying objects that are intended to deceive a radar operator into believing that they are actually aircraft. They are especially dangerous because they ...

  5. List of radar types - Wikipedia

    en.wikipedia.org/wiki/List_of_radar_types

    The radar measures the distance to the reflector by measuring the time of the round trip from emission of a pulse to reception, dividing this by two, and then multiplying by the speed of light. To be accepted, the received pulse has to lie within a period of time called the range gate .

  6. Radar cross section - Wikipedia

    en.wikipedia.org/wiki/Radar_cross_section

    Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. [1] An object reflects a limited amount of radar energy back to the source. The factors that influence this include: [1] the material with which the target is made;

  7. Naval Decoy IDS300 - Wikipedia

    en.wikipedia.org/wiki/Naval_Decoy_IDS300

    Naval Decoy IDS300 (Inflatable Decoy System) is a passive, off-board, octahedral, corner reflector decoy of the Royal Navy's Type 45 destroyer and the US Navy's Arleigh Burke-class destroyer, forming part of a layered defence to counter anti-ship missiles. [1] Unlike chaff, the decoy is persistent and will float for up to three hours in sea ...

  8. Radar - Wikipedia

    en.wikipedia.org/wiki/Radar

    Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.

  9. AN/SPG-62 - Wikipedia

    en.wikipedia.org/wiki/AN/SPG-62

    The AN/SPG-62 is a continuous wave fire-control radar developed by the United States, and it is currently deployed on warships equipped with the Aegis Combat System. [1] It provides terminal target illumination for the semi-active SM-2MR/ER and ESSM Block 1 surface-to-air missiles.
