    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 ...

    True color image of the Earth from space. This image is a composite image collected over 16 days by the MODIS sensor on NASA’s Terra satellite. NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019.

  4. 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.

  5. History of radar - Wikipedia

    en.wikipedia.org/wiki/History_of_radar

    If the radar antenna on an aircraft is aimed downward, a map of the terrain is generated, and the larger the antenna, the greater the image resolution. After centimeter radar came into being, downward-looking radars – the H2S ( L-Band) and H2X (C-Band) – provided real-time maps used by the U.S. and Britain in bombing runs over Europe at ...

  6. 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.

  7. Weather satellite - Wikipedia

    en.wikipedia.org/wiki/Weather_satellite

    GOES-16, a United States weather satellite of the meteorological-satellite service. 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 ...

  8. RADARSAT - Wikipedia

    en.wikipedia.org/wiki/RADARSAT

    The goal of this project was to produce a satellite for earth observation by way of a Synthetic Aperture Radar, which is an advanced radar sensor and powerful microwave instrument capable of producing high quality images of the Earth during day or night and across a wide range of weather conditions including cloud cover, smoke, and haze. [2]

  9. Spaceborne Imaging Radar - Wikipedia

    en.wikipedia.org/wiki/Spaceborne_Imaging_Radar

    Taken from Space Shuttle, 15 April 1994. The Spaceborne Imaging Radar ( SIR) – full name 'Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR)', [1] is a synthetic aperture radar which flew on two separate shuttle missions. Once from the Space Shuttle Endeavour in April 1994 on ( STS-59) and again in October 1994 on ( STS ...
