Synthetic Aperture Radar. A radar imaging instrument which provides a penetrating illumination of radio waves, and is capable of imaging surfaces covered by clouds and haze. SAR images are constructed of a matrix where lines of constant distance or range intersect with lines of constant Doppler shift. 2, record 1, English, - synthetic%2Daperture%20imaging%20radar

Radar imaging systems used in remote sensing applications consist of an air or space borne antenna. These antennas transmit and/or receive radar signals in order to produce imagery at a fine enough resolution for image interpreters to identify physical features on the Earth's surface. 3, record 1, English, - synthetic%2Daperture%20imaging%20radar

Un radar à synthèse d'ouverture (RSO) est un radar qui effectue un traitement des données reçues afin d'améliorer la résolution azimutale. Le traitement effectué permet d'affiner l'ouverture de l'antenne. On parle donc de synthèse d'ouverture. D'où le nom de ce type de système. Les radars à synthèse d'ouverture sont donc à opposer aux «radars à ouverture réelle» (RAR ou real aperture radar en anglais) pour lesquels la résolution azimutale est simplement obtenue en utilisant une antenne d'émission/réception possédant un lobe d'antenne étroit dans la direction azimutale. 2, record 1, French, - radar%20imageur%20%C3%A0%20synth%C3%A8se%20d%27ouverture

Les systèmes radar imageurs utilisés en télédétection consistent en une antenne installée sur un avion ou un satellite. Ces antennes émettent et/ou reçoivent des signaux radar qui sont traités pour produire des images d'une résolution suffisamment fine pour permettre aux interprètes d'identifier des éléments géographiques à la surface de la Terre. 3, record 1, French, - radar%20imageur%20%C3%A0%20synth%C3%A8se%20d%27ouverture
