  2. PAVE PAWS - Wikipedia

    en.wikipedia.org/wiki/PAVE_PAWS

    The first letter of the three-letter code denotes the type of platform hosting the electronic device, where A=Aircraft, F=Fixed (land-based), S=Ship-mounted, and T=Ground transportable. The second letter indicates the type of equipment, where P=Radar (pulsed), Q=Sonar, R=Radio, and Y=Data Processing

  3. Solid State Phased Array Radar System - Wikipedia

    en.wikipedia.org/wiki/Solid_State_Phased_Array...

    The Solid State Phased Array Radar System is a phased array radar with 2500 "solid state transmitter" modules. [6] It began replacing PAVE PAWS when the first AN/FPS-115 face was taken off-line for the radar upgrade. New AN/FPS-123 Early Warning Radars became operational in (Beale) and (Cape Cod) in each base's existing PAVE PAWS "Scanner ...

  4. Radar - Wikipedia

    en.wikipedia.org/wiki/Radar

    Radar is a system that uses radio waves to determine the distance ( ranging ), 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. Radar remote sensing - Wikipedia

    en.wikipedia.org/wiki/Radar_remote_sensing

    Radar remote sensing is a type of active remote Sensing which uses electromagnetic energy backscattered from ground targets to extract physical and dielectric behavior. [1] It is different from passive remote sensing, the most common type, as the electromagnetic radiation (EMR) is produced by the emitters and they transmit radiation at radio ...

  6. Radio navigation - Wikipedia

    en.wikipedia.org/wiki/Radio_navigation

    Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth, either the vessel or an obstruction. [1] [2] Like radiolocation, it is a type of radiodetermination . The basic principles are measurements from/to electric beacons, especially.

  7. Automatic identification system - Wikipedia

    en.wikipedia.org/wiki/Automatic_identification...

    The automatic identification system ( AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to receive AIS signatures, the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision ...

  8. Radiolocation - Wikipedia

    en.wikipedia.org/wiki/Radiolocation

    Radiolocation. Radiolocation, also known as radiolocating or radiopositioning, is the process of finding the location of something through the use of radio waves. It generally refers to passive uses, particularly radar —as well as detecting buried cables, water mains, and other public utilities.

  9. History of radar - Wikipedia

    en.wikipedia.org/wiki/History_of_radar

    A radio-based device for remotely indicating the presence of ships was built in Germany by Christian Hülsmeyer in 1904. This has been recognized by the Institute of Electrical and Electronics Engineers as the invention of the first working radar system by inauguration of an IEEE Historic Milestone in October 2019.
