L’antennerie acoustique, aussi appelée formation de voies, est une technique d’identification acoustique basée sur un modèle de propagation analytique entre les sources de bruit et les microphones, la fonction de Green. Dans le cas de l’étude de sources aéroacoustiques en configuration réaliste, le milieu de propagation entre les sources et les microphones est la plupart du temps constitué d’un écoulement inhomogène et/ou d’une géométrie complexe. La fonction de Green n’est alors généralement pas connue et l’utilisation d’une fonction non adaptée conduit à une localisation ainsi qu’une mesure du niveau acoustique des sources erronées. L’objectif de cette thèse est le développement d’une méthode permettant d’estimer, grâce au code de propag...
