Amplitude goniometer and associated platform

An amplitude goniometer comprising P receiver channels, P being an integer greater than or equal to 2, each receiver channel being identified by an index p corresponding to a given angular order, the index p being an integer between 0 and P−1, each receiver channel including an antenna coupled to a receiver chain, each receiver chain being followed by at least two digital receiver modules each comprising an analog-digital conversion module, each analog-digital conversion module being associated with a respective sampling frequency, each sampling frequency not complying with the Shannon criterion and not being a multiple of one of the other sampling frequencies, N being the number of sampling frequencies associated with the analog-digital conversion modules (22) belonging to the P receiver channels, N being greater than or equal to 2, each sampling frequency being referenced by an index n, the index n being between 0 and N−1, the amplitude goniometry estimator working from amplitudes of the signals originating from at least Q adjacent receiver channels among the P receiver channels, Q being an integer at most equal to P, the sampling frequencies being associated with the analog-digital conversion modules of these Q adjacent receiver channels.
