Les développements récents visent d'une part à augmenter la qualité de la correction afin d'imager des exoplanètes, et d'autre part à étendre le champ corrigeable. [...] l'OA [optique adaptative] peut souffrir de deux limitations importantes dues à la luminosité limitée des sources astronomiques et aux effets d'anisoplanétisme [...] En effet, l'AFO [analyseur de front d'onde] doit détecter une certaine quantité de photons pour effectuer correctement la mesure. Il faut donc disposer d'une source suffisamment brillante, dite étoile guide. Souvent l'objet observé est trop faiblement lumineux, il faut alors chercher une étoile brillante environnante mais hélas à proximité immédiate à cause de l'anisoplanétisme, réduisant sérieusement la couverture du ciel.  2, record 1, French, - %C3%A9toile%20guide

ENVISAT/ASAR may be calibrated using the ERS [European Remote Sensing Satellite] instrument. Two SAR [synthetic aperture radar] images of the same area are required and at least one strong point-like target must be visible in both scenes. The target response should originate from the same stable scatterer. For the technique a very coarse digital elevation model(DEM) of the scene is suitable.

The angle defined by the incident radar beam and the vertical (normal) to the intercepting surface.  3, record 12, English, - incidence%20angle

Record number: 12, Textual support number: 1 CONT

The incidence angle is commonly used to describe the angular relationship between the radar beam and the ground, surface layer or a target. A change of the radar illumination angle often affects the radar backscattering behaviour of a surface or target. The incidence angle changes across the radar image swath; it increases from near range to far range. In the case of satellite radar imagery, the change of incidence angle for flat terrain across the imaging swath tends to be rather small, usually on the order of several degrees. In the case of an inclined surface(slope), the local incidence angle is defined as the angle between the incident radar beam and a line that is normal to that surface. The local incidence angle determining, in part, the brightness, or image tone, for each picture element(pixel) and slope facet, is a key element in the prominent rendition of terrain features in radar imagery.  3, record 12, English, - incidence%20angle
