Abstract
(EN)
Disclosed is a two-step method for estimating an angle of arrival on the basis of a lens antenna. The disclosed method comprises: step (a) for selecting the antenna having the greatest power from among N signals received via N antennas after passing through a lens; and step (b) for estimating a more precise angle of arrival by using the relationship between two adjacent signals of the biggest signal in step (a).
(FR)
La présente invention porte sur un procédé en deux étapes permettant d'estimer un angle d'arrivée sur la base d'une antenne à lentille. Le procédé selon l'invention comprend : une étape (a) consistant à sélectionner l'antenne ayant la puissance la plus élevée parmi N signaux reçus par le biais de N antennes après avoir traversé une lentille ; et une étape (b) consistant à estimer un angle d'arrivée plus précis en utilisant la relation entre deux signaux adjacents du signal le plus important à l'étape (a).
