METHOD FOR LOCATING A BEACON BY ANGLES OF ARRIVAL

WIPO Patent Application WO/2017/084834

A3

The invention relates to a method for locating a beacon (X) which consists in performing R sequences, R being an integer no lower than 2, each including receiving, on a first antenna array (A1) and on a second antenna array (A2), a signal from the beacon (X), the signals of the R sequences having different wavelengths, and calculating a first function for estimating the angles of arrival of the signal on the first antenna array (A1) and a second function for estimating the angles of arrival of the signal on the second antenna array (A2), and in correlating the R first estimation functions with one another, and the R second estimation functions with one another, so as to determine a first angle (φ1) between the beacon (X) and the first array (A1), and a second angle (φ2) between the beacon (X) and the second array (A2), respectively.
