Abstract
L'invention concerne les dispositifs d'atterrissage aux instruments. Le réseau d'antennes de l'invention comporte trois éléments 11, 12 et 13 disposés verticalement avec un écartement uniforme. Les phases et les amplitudes des signaux SBO et CSB qui attaquent les différents éléments sont choisies de façon à réduire au minimum la longueur du plan de sol nécessaire, ce qui atténue la sensibilité aux signaux parasites provenant de réflexions sur des obstacles proches. Application aux dispositifs d'atterrissage aux instruments destinés aux sites à faible dégagement au niveau du sol.
