Abstract

L'invention concerne un procédé et un appareil de test d'antenne à partir d'une plate-forme mobile, et un dispositif de traitement d'informations. La plate-forme mobile porte une antenne émettrice ; lors de son déplacement selon une trajectoire de déplacement cible dans un plan à tester, la plateforme mobile transmet un signal cible à une antenne à tester au moyen de l'antenne émettrice. Le procédé comprend les étapes consistant à : pendant le déplacement de la plate-forme mobile, déterminer des informations d'angle de l'antenne émettrice dans ledit plan par rapport à l'antenne à tester ; acquérir l'intensité de signal reçu du signal cible reçu par l'antenne à tester à un angle correspondant aux informations d'angle ; et déterminer, conformément aux informations d'angle et de l'intensité de signal reçu, un diagramme directionnel de l'antenne à tester sur ledit plan. Au moyen des modes de réalisation de la présente invention, la plate-forme mobile peut être conçue pour effectuer des tests en champ lointain d'antennes, rapidement et avec de faibles coûts.
