2. 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.

   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. 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.

5. Radar navigation - Wikipedia

   en.wikipedia.org/wiki/Radar_navigation

   Radar ranges and bearings can be very useful for navigation. Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation.When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a ...

6. Google Earth - Wikipedia

   en.wikipedia.org/wiki/Google_Earth

   Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and ...

7. Radar MASINT - Wikipedia

   en.wikipedia.org/wiki/Radar_MASINT

   The AN/ZPQ-1 uses a radar signal in the 10 – 20 GHz J-band, and can work in strip map, spot map, and MTI modes. These modes are applicable to a wide range of MASINT sensors. Strip map imaging observes terrain parallel to the flight path or along a specified ground path. Resolution depends on range and swath width, and can vary from 0.3 to 1.0 ...
