The brightness of an object depends not only on its luminance but also on that of its surroundings. For example, an object of uniform luminance will appear brighter against a dark background than against a bright background.

CONT

Brightness may be a result of variations in tone, texture, or in the case of radar imagery, radar artifacts. The topography and surface roughness of the terrain will affect the image brightness. Where the local incidence angle is large, the image will be dark. Conversely, the image will be brighter where the local incidence angle is small.

OBS

radar brightness: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

PHR

Radar brightness of the target.

PHR

Variation in radar brightness.

CONT

La brillance d'un élément sur une image radar est fonction de la portion de l'énergie transmise qui retourne au radar à partir de la cible à la surface. La magnitude de l'intensité de cette énergie rétrodiffusée dépend de la manière dont l'énergie radar interagit avec la surface, en fonction de plusieurs variables ou paramètres. Ces paramètres incluent les caractéristiques particulières des systèmes radars (fréquence, polarisation, géométrie de visée, etc.) ainsi que les caractéristiques de la surface (type de couverture, topographie, relief, etc.).

OBS

brillance radar : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

PHR

Brillance de la scène visée.

PHR

Variation spatiale de la brillance.
