Measurement of the Total Radiated Power Contributions in a Reverberation Tent
A method for the total radiated power (TRP) measurement of multiple non-correlated emission sources in a reverberation tent is proposed. The method can resolve the contributions of each source, which is critical for the noise source identification in complex electronic systems. Blind source separation (BSS) is implemented in relatively short periods to avoid the influence from the stirring of the reverberation tent. The BSS results can be resolved to the TRP of the individual sources through an averaging cancellation method. The method might be useful in situations when no direct access to the sources is possible or desirable to obtain a signal reference and all measurement probes should be placed in the far-field zone.
