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 ...

3. NISAR (satellite) - Wikipedia

   en.wikipedia.org/wiki/NISAR_(satellite)

   The NASA-ISRO Synthetic Aperture Radar, or NISAR satellite, will use advanced radar imaging to map the elevation of Earth's land and ice masses four to six times a month at resolutions of 5 to 10 meters. [9] It is designed to observe and measure some of the planet's most complex natural processes, including ecosystem disturbances, ice-sheet ...

4. 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 ...

5. 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.

6. Radar remote sensing - Wikipedia

   en.wikipedia.org/wiki/Radar_remote_sensing

   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 ...

7. Capella Space - Wikipedia

   en.wikipedia.org/wiki/Capella_Space

   Capella Space is an American space company with satellite and declassified SAR data solutions for government and commercial use. It offers space-based radar Earth observation satellites equipped with synthetic-aperture radar that can collect imagery through clouds and at night. [1] The company is based in San Francisco, California with offices ...

8. Weather radar - Wikipedia

   en.wikipedia.org/wiki/Weather_radar

   Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).

9. 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 ...
