1. A receiving system for a multi-sensor antennas, comprising: at least one set of channel filters ( 310 i, 710 i,k, i&equals;1... N) filtering signals X i (t, f) received at the different antenna sensors, said signals possibly including a desired signal (S 1 (t, f)), a summer ( 350, 750 ) summing the signals (V i (t, f), V i,k (t, f); i&equals;1... N) filtered by the channel filters and emitting an antenna output signal Y(t, f), at least one calculating module ( 320, 720 ) receiving either the sensor signals and aligning them in phase, or the signals filtered by the channel filters, said module estimating the transfer function of an optimum filter (W(t, f), W k V(t, f) in a manner to minimize the squared difference between the antenna output signal filtered by said filter and the desired signal, characterized in that said receiving system moreover includes at least one statistical analysis module ( 330, 730 ) for the frequency values of the transfer function.
