Title (EN) METHOD FOR ACQUIRING AN IMAGE BY OVERSAMPLED PUSH-BROOM SCANNING
(FR) PROCEDE POUR L'ACQUISITION D'UNE IMAGE PAR BALAYAGE POUSSE-BALAI SURECHANTILLONNE
Abstract:
(EN) The invention concerns a method for acquiring an image by oversampled push-broom scanning from a satellite-borne vehicle or aircraft carrying at least a load transfer sensor bar, characterised in that it consists in controlling the attitude and the vehicle rolling, pitching and yawing angular speeds such that the longitudinal and lateral ground speeds of the bar verify: (a), (b) in which Vref = P/Ti, P being the bar ground step, Ti the sampling period, and m and $i(l) two whole numbers.
(FR) Procédé pour l'acquisition d'une image par balayage pousse-balai à partir d'un véhicule satellitaire ou aérien portant au moins une barrette de capteurs de type à transfert de charge, caractérisé en ce que l'on commande l'attitude et les vitesses angulaires de roulis, tangage et lacet du véhicule pour que les vitesses longitudinale et latérale au sol de la barrette vérifient (a), (b) où Vref = P/Ti, P étant le pas au sol de la barette, Ti la période d'échantillonnage, m et $i(l) deux entiers.
