Abstract

Procédé de géolocalisation d’un émetteur de signaux radioélectriques par un engin volant et système de géolocalisation associé La présente invention concerne un procédé de géolocalisation d’un émetteur (13) de signaux radioélectriques par un engin volant (10) tractant une antenne linéique (20) définissant dans chaque position de l’engin volant (10) une position de son centre de phases et un axe d’antenne. Le procédé comportant les étapes de réception des signaux radioélectriques issus d’un émetteur (13) et estimation à chaque position, de l’angle entre la direction d’arrivée des signaux radioélectriques issus de l’émetteur (13) et l’axe d’antenne correspondant, pour obtenir une valeur angulaire estimée, et d’estimation de la position de l’émetteur (13) à partir de l’ensemble des valeurs angulaires estimées correspondant aux positions correspondantes de l’engin volant (10), aux positions correspondantes des centres de phases et aux axes d’antenne correspondants.
