  3. 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 ...

  4. Radar calibration satellite - Wikipedia

    en.wikipedia.org/wiki/Radar_calibration_satellite

    Active calibration satellites are equipped with transponders that emit a signal on command. The ground radar station submits a transmit command and takes a measurement of the satellite's location. The transponder's signal is received by a radar receiver and combined with the satellite's ephemeris data to calculate the satellite's actual ...

  5. Sentinel-1A - Wikipedia

    Sentinel-1A. Sentinel-1A is a European radar imaging satellite launched in 2014. It is the first Sentinel-1 satellite launched as part of the European Union 's Copernicus programme. The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions. It analyzes many phenomena occurring on Earth ...

  6. Space-based radar - Wikipedia

    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 ...

  7. Marine radar - Wikipedia

    en.wikipedia.org/wiki/Marine_radar

    Marine radar. Animation of typical rotating X band marine radar antenna on ship. It radiates a narrow vertical fan-shaped beam of microwaves perpendicular to the long axis of the antenna, horizontally out to the horizon. With each rotation the beam scans the surrounding surface. Any ships or obstructions reflect microwaves back to the antenna ...

  8. Radarsat-1 - Wikipedia

    en.wikipedia.org/wiki/RADARSAT-1

    RADARSAT-1 used a synthetic aperture radar (SAR) sensor to image the Earth at a single microwave frequency of 5.3 GHz, in the C band (wavelength of 5.6 cm). The SAR support structure was designed and manufactured by Northrop Grumman Astro Aerospace and deployed to 15 m (49 ft) in length on orbit. Unlike optical satellites that sense reflected ...

  9. RADARSAT Constellation - Wikipedia

    en.wikipedia.org/wiki/RADARSAT_Constellation

    The RADARSAT Constellation Mission (RCM) is a three-spacecraft fleet of Earth observation satellites operated by the Canadian Space Agency.The RCM's goal is to provide data for climate research and commercial applications including oil exploration, fishing, shipping, etc. With satellites smaller than RADARSAT-2, the RCM will provide new applications—made possible through the constellation ...
