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. 8, record 4, French, - radar%20%C3%A0%20synth%C3%A8se%20d%26rsquo%3Bouverture

Once the SAR wavelength and orbital altitude have been specified, the antenna has to meet a certain minimum aperture area dictated by range and azimuth ambiguity considerations. The challenge is to develop clever sub-pulse coding schemes that make it possible to suppress the ambiguities, thereby reducing the requirements on antenna size by a factor of 5 or 10. 3, record 5, English, - azimuth%20ambiguity

Ambiguïté en azimut. Si l'image générée est bidimensionnelle, l'information reçue est quant à elle unidimensionnelle. L'antenne ne fait que stocker une succession d’échos en fonction du temps bien qu'ils soient stockés dans une matrice bidimensionnelle. Seule une connaissance approchée et a priori de la distance de la zone à imager permet de calibrer les délais d’acquisition et d’assigner la bonne position en azimut pour une ligne. Si celle-ci est mal connue, le lieu imagé ne sera pas celui attendu. Mais surtout, le lobe principal «éclairant» tout de même la zone étudiée, des échos risquent de revenir plus tôt ou plus tard et donc, pendant une autre phase d’acquisition. Ils seront [alors] associés à une autre ligne, c'est-à-dire à une autre position azimutale. 3, record 5, French, - ambigu%C3%AFt%C3%A9%20en%20azimut

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 10, French, - radar%20imageur%20%C3%A0%20synth%C3%A8se%20d%26rsquo%3Bouverture

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 10, French, - radar%20imageur%20%C3%A0%20synth%C3%A8se%20d%26rsquo%3Bouverture

Traditional methods for acquiring topographic data typically rely on aerial photogrammetry, where measurement of the terrain surface below forest canopy is difficult and error prone. The recent emergence of airborne P-band interferometric synthetic aperture radar (IFSAR), a high -resolution, microwave remote sensing technology, has the potential to provide significantly more accurate terrain models in forested areas. Low-frequency, P-band radar energy physically penetrates through the vegetation canopy and reflects from the underlying terrain surface, allowing for accurate measurement of the terrain surface elevation even in areas with dense forest cover. 3, record 11, English, - interferometric%20synthetic%20aperture%20radar

L’émergence récente des données interférométriques radar aéroporté à synthèse d’ouverture en bande P (IFSAR), une technologie de télédétection micro-onde à haute résolution, pourrait fournir des modèles d’altitude significativement plus précis dans les zones forestières. L’énergie à basse fréquence du radar en bande P pénètre physiquement à travers le couvert de végétation et est réfléchie par la surface sous-jacente du terrain permettant la mesure précise de l’altitude à la surface du terrain, même dans les zones de couvert forestier dense. 3, record 11, French, - radar%20interf%C3%A9rom%C3%A9trique%20%C3%A0%20synth%C3%A8se%20d%26rsquo%3Bouverture
