Title (EN) MULTI-SPECTRAL DIRECTION FINDING SENSOR
(FR) DÉTECTEUR RADIOGONIOMÉTRIQUE MULTISPECTRAL
Abstract:
(EN) A method and apparatus for determining the position of a target are disclosed. The method includes collecting onboard the platform a first set optical radiation in a first bandwidth and a second set of optical radiation in a second bandwidth reflected from a field of view; and determining the position of the target from the difference between the detected first and second sets of optical radiation. The apparatus includes a pair of detection channels a pair of detection channels, each of which further includes at least three optical channels, each detection channel capable of collecting onboard the platform a first set optical radiation in a first bandwidth and a second set of optical radiation in a second bandwidth, respectively, reflected from a field of view. The apparatus further includes a plurality of electronics capable of determining the position of the target from the difference between the detected first and second sets of optical radiation.
(FR) La présente invention concerne un procédé et un appareil servant à déterminer la position d'une cible. Le procédé consiste à recueillir et à intégrer sur la plate-forme un premier ensemble de rayonnements optiques d'une première largeur de bande et un second ensemble de rayonnements optiques d'une seconde largeur de bande réfléchis à partir d'un champ d'observation, ainsi qu'à déterminer la position de la cible d'après la différence entre le premier et le second ensemble de rayonnements optiques détectés. L'appareil comprend deux canaux de détection, incorporant chacun au moins trois porteuses optiques. Chaque canal de détection recueille respectivement sur la plate-forme un premier ensemble de rayonnements optiques d'une première largeur de bande et un second ensemble de rayonnements optiques d'une seconde largeur de bande, réfléchis à partir d'un champ d'observation. L'appareil comporte en outre une pluralité de composants électroniques permettant de déterminer la position de la cible d'après la différence entre le premier et le second ensemble de rayonnements optiques détectés.
