Abstract: The present invention relates to an amplitude goniometer comprises P receiver channels, P being greater than or equal to 2, each receiver channel being identified by an index p, each receiver channel comprising an antenna coupled to a receiver chain followed by at least two digital receiver modules each comprising an analogue-to-digital conversion module associated with a respective sampling frequency, each sampling frequency not complying with the Shannon criterion and not being a multiple of another frequency, N being the number of frequencies, N being greater than or equal to 2, each frequency being referenced by an index n, the amplitude goniometry estimator working from the amplitudes of the signals originating from at least Q adjacent receiver channels of the P receiver channels, Q being at most equal to P, the sampling frequencies being associated with the analogue-to-digital conversion modules of the Q adjacent receiver channels.
