What is Synthetic Aperture Imaging?

Synthetic aperture radar (SAR) imaging, is a technique that allows us to remotely map the reflectivity of objects or environments with high spatial resolution, through the emission and reception of electromagnetic (EM) signals.

Does a radar satellite need sun illumination to acquire images?

Both satellites used as radar interferometer for WorldDEM™. Electro-optical systems are passive, which means they require the illumination of the sun for imaging. Radar, however, is an active remote sensing system, which means it provides its own energy source to illuminate the imaging area.

What does synthetic aperature radar mean?

A synthetic-aperture radar is an imaging radar mounted on a moving platform. Electromagnetic waves are transmitted sequentially, the echoes are collected and the system electronics digitizes and stores the data for subsequent processing. As transmission and reception occur at different times, they map to different positions.

What is synthetic aperture radar antenna?

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. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional beam-scanning radars.

What is the abbreviation for synthetic aperture radar?

Synthetic Aperture Radar is abbreviated as SAR. (also SEVIRI) GPS Global Positioning System. IT Information Technology. LAN Local Area Network. NOAA National Oceanic and Atmospheric Administration. EOS Earth Observing System. GOES Geostationary Operational Environmental Satellite. NASA National Aeronautics and Space Administration.

What is synthetic aperture sonar?

Synthetic aperture sonar ( SAS ) is a form of sonar in which sophisticated post-processing of sonar data are used in ways closely analogous to synthetic aperture radar.
