Abstract (en)
[origin: WO03071293A1] The invention relates to a method for sampling at least one antenna (2) comprising a receiver module (8) and a coupling module (10) that is arranged between the antenna (2) and the receiver module (8). A noise signal (S) is fed to the antenna (2) and the receiver module (8) as a sampling signal via the coupling module (10). An instantaneous transmission coefficient (UV) indicating the relationship between a first noise signal, which reaches a sampling module (12) via a first path (S, S1) without transiting through the at least one antenna (2), and a second noise signal, which reaches said sampling module (12) from the noise source (18) via a second path (S', S2) transiting through the at least one antenna (2), is then determined via the sampling module (12) and is compared with a reference transmission coefficient (Uvinorm) stored in a transmission matrix (14). Also disclosed is a system for carrying out the inventive method.
