  2. Passive radar - Wikipedia

    en.wikipedia.org/wiki/Passive_radar

    Passive radar. Passive radar (also referred to as parasitic radar, passive coherent location, passive surveillance, and passive covert radar) is a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals.

  3. Synthetic-aperture radar - Wikipedia

    en.wikipedia.org/wiki/Synthetic-aperture_radar

    Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.

  4. Rajendra Radar - Wikipedia

    en.wikipedia.org/wiki/Rajendra_radar

    Rajendra is a slewable passive phased array radar used for 3-D target detection, multi target tracking and multiple missile guidance under extreme hostile EW environment. . It makes use of a passive phased array to search a volume of space, distinguish between hostile and friendly targets, automatically track up to 64 targets and command one of several launchers to engage up to 4 targets ...

    en.wikipedia.org/wiki/Passive_electronically...

    The velocity of the radio waves is shown slowed down enormously. A passive electronically scanned array (PESA), also known as passive phased array, is an antenna in which the beam of radio waves can be electronically steered to point in different directions (that is, a phased array antenna), in which all the antenna elements are connected to a ...

  6. Low-probability-of-intercept radar - Wikipedia

    en.wikipedia.org/wiki/Low-probability-of...

    A low-probability-of-intercept radar (LPIR) is a radar employing measures to avoid detection by passive radar detection equipment (such as a radar warning receiver (RWR), or electronic support receiver) while it is searching for a target or engaged in target tracking. This characteristic is desirable in a radar because it allows finding and ...

    The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. [1]

  8. AN/TPS-75 - Wikipedia

    en.wikipedia.org/wiki/AN/TPS-75

    AN/TPS-75. AN/TPS-75 radars deployed at Tobyhanna Army Depot. The AN/TPS-75 is a transportable passive electronically scanned array air search 3D radar produced in the United States. It was originally designated the TPS-43E2. Although the antenna is a radically new design from the TPS-43, the radar van itself, which houses the transmitter ...
