  2. NEXRAD - Wikipedia

    en.wikipedia.org/wiki/NEXRAD

    NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...

    en.wikipedia.org/wiki/Space-based_radar

    Space-based radar (SBR) is a proposed constellation of active radar satellites for the United States Department of Defense. The SBR system would allow detection and tracking of aircraft, ocean-going vessels (similar to the Soviet US-A program), and potentially land vehicles from space. This information would then be relayed to regional and ...

  4. Weather satellite - Wikipedia

    en.wikipedia.org/wiki/Weather_satellite

    A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator). [1]

  6. Continuous-wave radar - Wikipedia

    en.wikipedia.org/wiki/Continuous-wave_radar

    Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal, allowing ...

  7. 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.

    6th Space Warning Squadron. Cape Cod Space Force Station is a United States Space Force station located in the northwest corner of Joint Base Cape Cod, United States, on Flatrock Hill in Bourne, Massachusetts. Cape Cod Space Force Station began construction in 1976 as Cape Cod Missile Early Warning Station and was renamed Cape Cod Air Force ...

  9. Imaging radar - Wikipedia

    en.wikipedia.org/wiki/Imaging_radar

    Imaging radar is an application of radar which is used to create two-dimensional images, typically of landscapes. Imaging radar provides its light to illuminate an area on the ground and take a picture at radio wavelengths. It uses an antenna and digital computer storage to record its images.
