When the beam has returned to the left side, its vertical position is lowered so that the beam will scan the next line down and not repeat the same line. This is accomplished by the vertical scanning motion of the beam, which is provided in addition to horizontal scanning. As a result of the vertical scanning, all the horizontal lines slope downward slightly from top to bottom. When the beam is at the bottom, vertical retrace returns the beam to the top to start the scanning sequence again. 4, record 4, English, - vertical%20scanning

Record number: 11, 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 11, 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 11, French, - impulsion%20radar
