Azimut (d’une direction en un lieu donné) : [...] angle dièdre formé entre les demi-plans limités par la verticale du lieu et contenant respectivement la direction de l’axe Y du repère cartographique (ou le Nord d’un repère géographique ou magnétique) et la direction dont on veut mesurer l’azimut [;] cet angle est mesuré dans le sens des aiguilles d’une montre (sens trigonométrique inverse), de 0 à 360°. 2, record 1, French, - azimut

L'image radar est référencée par deux coordonnées, appelées distance(liée au temps de propagation entre l'antenne et le réflecteur) et azimut(liée au numéro de l'impulsion). La résolution en distance est améliorée par compression d’impulsion, la résolution en azimut est améliorée par synthèse d’ouverture. 3, record 1, French, - azimut

Nous n’ exposerons pas ici les corrections effectuées sur le signal radar avant compression en azimut, rappelons néanmoins que la distorsion la plus importante, due au phénomène de migration en distance, est corrigée par un rééchantillonnage de l'image, de sorte que les contributions d’une cible donnée se trouvent ramenées dans une même ligne azimutale de l'image. 1, record 2, French, - ligne%20azimutale

[La] compression en azimut consiste donc à rassembler pour chaque cible l'information étalée en azimut. Cette technique exige une localisation précise des différentes contributions dans l'image. Or, celles-ci sont souvent étalées en distance. Ce phénomène[, ] appelé migration [...] doit être corrigé avant la compression en azimut si l'on veut que celle-ci s’effectue correctement. 3, record 3, French, - compression%20en%20azimut
