  2. Imaging radar - Wikipedia

    en.wikipedia.org/wiki/Imaging_radar

    In a radar image, one can see only the energy that was reflected back towards the radar antenna. The radar moves along a flight path and the area illuminated by the radar, or footprint, is moved along the surface in a swath, building the image as it does so. [1] Digital radar images are composed of many dots.

  3. Interferometric synthetic-aperture radar - Wikipedia

    en.wikipedia.org/wiki/Interferometric_synthetic...

    Interferometric synthetic aperture radar, abbreviated InSAR (or deprecated IfSAR), 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 [1] [2] [3] or aircraft.

  4. High Resolution Wide Swath SAR imaging - Wikipedia

    en.wikipedia.org/wiki/High_Resolution_Wide_Swath...

    Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to provide multiple imaging modes for recording images with different swath width, resolution and polarizations, see the figure for more details. In stripmap mode (spatial resolution of 3m), it needs 10 weeks to map global Earth's landmass.

  5. Weather radar - Wikipedia

    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.).

  6. Inverse synthetic-aperture radar - Wikipedia

    en.wikipedia.org/wiki/Inverse_synthetic-aperture...

    Inverse synthetic-aperture radar (ISAR) is a radar technique using radar imaging to generate a two-dimensional high resolution image of a target. It is analogous to conventional SAR , except that ISAR technology uses the movement of the target rather than the emitter to create the synthetic aperture . [ 1 ]

  7. Volumetric Imaging and Processing of Integrated Radar

    en.wikipedia.org/wiki/Volumetric_Imaging_and...

    The result of this process is a three-dimensional image of the storm, which may be rotated and viewed from any angle. If imagery is zoomed in at an adequate range, actual weather satellite data can be superimposed. VIPIR images can be constructed from multiple sources, including Doppler weather radar and NEXRAD. [3]

  8. Spaceborne Imaging Radar - Wikipedia

    en.wikipedia.org/wiki/Spaceborne_Imaging_Radar

    The radar was run by NASA's Space Radar Laboratory. SIR utilizes 3 radar frequencies: L band (24 cm wavelength), C band (6 cm) and X band (3 cm), [1] allowing for study of geology, hydrology, ecology and oceanography. Comparing radar images to data collected by teams of people on the ground as well as aircraft and ships using simultaneous ...

  9. Weather satellite - Wikipedia

    en.wikipedia.org/wiki/Weather_satellite

    Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. [2] Smoke from fires in the western United States such as Colorado and Utah have also been monitored. El Niño and its effects on weather are
