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 1, French, - radar%20%C3%A0%20synth%C3%A8se%20d%27ouverture

Record number: 3, Textual support number: 1 OBS
In synthetic aperture radar(SAR) imaging, microwave pulses are transmitted by an antenna towards the Earth surface. The microwave energy scattered back to the spacecraft is measured. The SAR makes use of the radar principle to form an image by utilising the time delay of the backscattered signals. In real aperture radar imaging, the groud resolution is limited by the size of the microwave beam sent out from the antenna. Finer details on the ground can be resolved by using a narrower beam. The beam width is inversely proportional to the size of the antenna, i. e. the longer the antenna, the narrower the beam. 2, record 3, English, - radar%20pulse

La génération d'une image SAR nécessite la combinaison de deux mécanismes de balayage. Tout d'abord un balayage latéral. Chaque impulsion se propopage à une vitesse égale à celle de la lumière (c = 3.108 m.s-1) selon la direction de visée du satellite (across track), l'écho reçu au niveau de l'antenne est ensuite échantillonné à la fréquence fe (18.96 Mhz pour ERS-1). Simultanément, la scène est balayée dans le sens de déplacement du satellite (along track) à la fréquence d'émission des impulsions notée fp ou PRD (Pulse Rate Frequency) : (entre 1640 et 1720 Hz, par pas de 2 Hz dans le cas d'ERS-1). Les échelles de grandeur des divers mécanismes mis en jeux étant différentes, nous pouvons les supposer indépendants entre eux. Le signal reçu peut être ainsi organisé dans une matrice bi-dimensionnelle, où les paramètres de temps et de distance sont représentés respectivement en ligne par le cadencement des impulsions (PRF) et en colonne par la position des échos sur la ligne, une ligne étant acquise à chaque émission d'une impulsion radar (ou pulse). Une colonne de l'image représentera l'ensemble des réponses des réflecteurs placés à une distance donnée de l'antenne (distance radiale). Sa position sur la ligne est linéairement liée au temps mis par l'onde radar à lui revenir après s'être réfléchie sur le point cible, le radar étant considéré immobile durant ce temps. 2, record 3, French, - impulsion%20radar

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 4, English, - interferometric%20synthetic%20aperture%20radar
