Seasat [3] was the first Earth-orbiting satellite designed for remote sensing of the Earth's oceans and had on board one of the first spaceborne synthetic-aperture radar (SAR). ). The mission was designed to demonstrate the feasibility of global satellite monitoring of oceanographic phenomena and to help determine the requirements for an operational ocean remote sensing satellite sys
Synthetic aperture radar was first used by NASA on JPL's Seasat oceanographic satellite in 1978 (this mission also carried an altimeter and a scatterometer); it was later developed more extensively on the Spaceborne Imaging Radar (SIR) missions on the space shuttle in 1981, 1984 and 1994.
The Radar-C system was built and operated by NASA's Jet Propulsion Laboratory (JPL). The mission was a joint work of NASA with the German and Italian space agencies. [ 2 ] [ 3 ] Each of the week long mission scanned about 50 million square kilometers of the Earth's surface, (19.3 million square miles).
Space-based radar or spaceborne radar is a radar operating in outer space; orbiting radar is a radar in orbit and Earth orbiting radar is a radar in geocentric orbit. A number of Earth-observing satellites , such as RADARSAT , have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth .
The United States launched two Future Imagery Architecture (FIA) radar satellites into 122° inclined retrograde orbits in 2010 and 2012. The use of a retrograde orbit suggest that these satellites use synthetic aperture radar. [3] Earth-observing satellites may also be launched into a Sun-synchronous orbit, which is slightly retrograde. [8]
The Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) is a multi-frequency, multi-channel ice penetrating radar system that will be flown on board the Europa Clipper mission to Jupiter's moon Europa. REASON investigation will provide the first direct measurements of Europa's ice shell surface character and subsurface ...
Interferometric synthetic aperture radar (InSAR) is a radar technique used in geodesy and remote sensing. This geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface deformation or digital elevation , using differences in the phase of the waves returning to the satellite.
The Alaska Satellite Facility began as a single-purpose receiving station known as the Alaska Synthetic Aperture Radar (SAR) Facility [7] located in the Geophysical Institute (GI) at the University of Alaska Fairbanks. [8] The interest in space-borne SAR observations began in the U.S. with the success of the Seasat mission in 1978. [9] (There ...
