<p>The invention concerns a reception system for a multisensor antenna comprising: at least a set of channel filters ((310 i)(710i,k) i=1 N) filtering the signals Xi(t,f) received by the various sensors of the antenna, said signals capable on including a useful signal (S1(t,f)); an adder ((350, 370)) adding the filtered signals (Vi(t,f), Vi,k(t,f), i=1 N) by the channel filters and supplying an antenna output signal Y(t,f); at least a calculating module ((320)(720)) receiving ether the sensor signals and aligning them in phase or the signals filtered by the channel filters, said module estimating the transfer function of an optimal filter (W(t,f), Wk(t,f)) so as to minimise the quadratic deviation between the antenna output signal filtered by said filter and the useful signal. The invention is characterised in that it further comprises at least a statistical analysis module ((330)(730)) for frequency values of the transfer function.</p> |
