Abstract

La présente invention est appliquée au domaine des techniques d'antennes hyperfréquences. Elle concerne un procédé et un appareil pour régler des antennes dans un système à hyperfréquences multi-entrée multi-sortie. Le système comprend quatre unités d'extérieur, disposées de façon que seule une unité d'extérieur ait un angle d'antenne différent de l'angle des antennes des trois autres unités d'extérieur. Le procédé comprend les étapes consistant à : configurer une deuxième unité d'extérieur dans un état d'émission et configurer une première unité d'extérieur et une troisième unité d'extérieur dans un état de réception; déterminer si la différence de puissance des signaux hyperfréquences reçus par la première unité d'extérieur et la troisième unité d'extérieur est supérieure à un certain seuil; si ce n'est pas le cas, régler l'antenne d'une quatrième unité d'extérieur pour rendre l'angle de l'antenne de la quatrième unité d'extérieur cohérent avec celui des autres unités d'extérieur. Dans la présente invention, on combine deux unités d'extérieur pour former un saut et l'on détermine si les angles des antennes sont ou non cohérents en déterminant les signaux de lobes latéraux reçus, garantissant ainsi la cohérence entre les angles des antennes au niveau d'un nœud.
