Record number: 2, Textual support number: 1 CONT
One type of scanner is called a whiskbroom scanner also referred to as across-track scanners. It uses rotating mirrors to scan the landscape below from side to side perpendicular to the direction of the sensor platform, like a whiskbroom. The width of the sweep is referred to as the sensor swath. The rotating mirrors redirect the reflected light to a point where a single or just a few sensor detectors are grouped together. Whiskbroom scanners with their moving mirrors tend to be large and complex to build. The moving mirrors create spatial distortions that must be corrected with preprocessing by the data provider before image data is delivered to the user. An advantage of whiskbroom scanners is that they have fewer sensor detectors to keep calibrated as compared to other types of sensors. 5, record 2, English, - across%2Dtrack%20scanner

The different sources of this noise could be due to periodic drift or malfunction of the detector, or due to electronic interference among sensor components, or due to problem in the transmission and recording process. The noise, if present in any part of the image can either degrade or totally mask the true radiometric information contained by the digital image. Hence, noise removal is very essential before any preprocessing or analysis of the image could be done. 2, record 4, English, - image%20noise

Preprocessing is an important and diverse set of image preparation programs that act to offset problems with the band data and recalculate DN [Digital Number] values that minimize these problems. Among the programs that optimize these values are atmospheric correction(affecting the DNs of surface materials because of radiance from the atmosphere itself, involving attenuation and scattering) ;Sun illumination geometry; surface-induced geometric distortions; spacecraft velocity and attitude variations(roll, pitch, and yaw) ;effects of Earth rotation, elevation, curvature(including skew effects), abnormalities of instrument performance(irregularities of detector response and scan mode such as variations in mirror oscillations) ;loss of specific scan lines(requires destriping), and others. Once performed on the raw data, these adjustments require appropriate radiometric and geometric corrections. 2, record 6, English, - preprocessing

La première étape de prétraitement des données SAR correspond à la transformation des données 16 bits en données 8 bits et ce, afin de faciliter la manipulation ainsi que la combinaison avec les autres données optiques qui sont, généralement, sur 8 bits. La deuxième étape consiste à réduire le châtoiement inhérent aux images SAR [radar à synthèse d'ouverture] [...] La troisième étape comprend le prétraitement des données TM [Thematic Mapper] de Lansat dont le but vise essentiellement l'amélioration de la qualité des images. Cette étape est effectuée en trois phases : la superposition géométrique, le géocodage des images optiques comparées à une image SAR disponible de type GEC [Geocoded Ellipsoid Corrected] et, enfin, le rééchantillonnage des pixels à une résolution de 25 m. 2, record 6, French, - pr%C3%A9traitement
