Patent ID: 10585181

Abstract:
This method involves, for an array of at least two antennas pointing in different directions and the respective radiation patterns of which overlap one another, each antenna including at least two radiating elements so as to be able to work in a first operating mode associated with a first radiation pattern (Δ) and according to a second operating mode associated with a second radiation pattern (Σ): acquiring, for each antenna, a first signal (SΔi) corresponding to the first operating mode and a second signal (SΣi) corresponding to the second operating mode; determining, for each antenna, an opening half-angle (ρi) of a cone of possible directions of incidence from the amplitude of the first and second signals; calculating the bearing angle (Θ0) and/or the elevation angle (φ0) of the direction of incidence by intersection of the cones of possible directions of incidence determined for each antenna.
