    However, since humans reflect far less radar energy than metal does, these systems require sophisticated technology to isolate human targets and moreover to process any sort of detailed image. Through-the-wall radars can be made with Ultra Wideband impulse radar, micro- Doppler radar , and synthetic aperture radar (SAR).

    A radar is an electronic system used to determine and detect the range of target and maps various types of targets. This is a list of radars. This is a list of radars. Argentina

  4. 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.

  5. Early-warning radar - Wikipedia

    en.wikipedia.org/wiki/Early-warning_radar

    An early-warning radar is any radar system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as early as possible before the intruder reaches its target, giving the air defences the maximum time in which to operate.

  6. Passive radar - Wikipedia

    en.wikipedia.org/wiki/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.

  7. Multistatic radar - Wikipedia

    en.wikipedia.org/wiki/Multistatic_radar

    A multistatic radar system. A multistatic radar system contains multiple spatially diverse monostatic radar or bistatic radar components with a shared area of coverage. An important distinction of systems based on these individual radar geometries is the added requirement for some level of data fusion to take place between component parts.

  8. Primary radar - Wikipedia

    en.wikipedia.org/wiki/Primary_radar

    A primary radar or primary surveillance radar (PSR) is a conventional radar sensor that illuminates a large portion of space with an electromagnetic wave and detects the waves that reflect from targets within that space. The term thus refers to a radar system used to detect and localize potentially non-cooperative targets.

    In contrast, the beam of a PESA radar can rapidly be changed to point in a different direction, simply by electrically adjusting the phase differences between different elements of the passive electronically scanned array (PESA). In 1959, DARPA developed an experimental phased array radar called Electronically Steered Array Radar (ESAR). It was ...
