ABSTRACT:
The present invention relates to a receiving system for a multi-sensor antenna and comprising:at least one set of channel filters (310j, 710k, 1 . . . N) filtering the signals Xi(t,f) received by the different antenna sensors, where these signals may include a desired signal (Si(t,f));a summer (350, 720) summing the filtered signals [Vi(t,f)], where i=1 . . . N, by means of 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 (W(t,f), W k(t,f)) of an optimum filter in a manner to minimize the square difference between the antenna output signals filtered by said filter and the desired signal characterized in thatif furthermore comprises at least one statistical analysis module (330, 730) operating on the frequency values of the transfer function.
