Abstract

Procédé et dispositif d’estimation d’un angle d’arrivée de signal radioélectrique L’invention concerne un procédé et un dispositif d’estimation d’un angle d’arrivée d’un signal radioélectrique, mis en œuvre par un système de réception comportant une pluralité d’antennes de réception réparties régulièrement sur un cercle de manière à former un réseau circulaire d’antennes de réception, et adapté à calculer une première valeur d’angle d’arrivée estimée par goniométrie d’amplitude. Le procédé comporte des étapes de : -sélection (32) d’un triplet d’antennes de réception, comportant une antenne principale et deux antennes secondaires, -calcul (34) d’un premier déphasage de réception entre l’antenne principale et une première antenne secondaire, et d’un deuxième déphasage de réception entre l’antenne principale et une deuxième antenne secondaire ; - utilisation (38-48) de données de déphasages théoriques, associant des valeurs d’angle d’arrivée à des valeurs de premier déphasage et deuxième déphasage, et de ladite première valeur d’angle d’arrivée estimée, pour déterminer une valeur d’angle d’arrivée estimée finale, obtenue soit par goniométrie d’amplitude, soit par goniométrie de phase. Figure pour l'abrégé : Figure 2Method and device for estimating an angle of arrival of a radio signal The invention relates to a method and a device for estimating an angle of arrival of a radio signal, implemented by a reception system comprising a plurality of reception antennas distributed regularly over a circle so as to form a circular array of reception antennas, and adapted to calculate a first value of angle of arrival estimated by amplitude direction finding. The method comprises the steps of: -selection (32) of a triplet of reception antennas, comprising a main antenna and two secondary antennas, -calculation (34) of a first reception phase shift between the main antenna and a first secondary antenna, and a second reception phase shift between the main antenna and a second secondary antenna; - use (38-48) of theoretical phase shift data, associating angle of arrival values with values of first phase shift and second phase shift, and of said first estimated angle of arrival value, to determine a value d 'final estimated angle of arrival, obtained either by amplitude direction finding or phase direction finding.
