Diffuse Field Cross-Correlation in a Reverberation Chamber

Résumé

The cross-correlation between diffuse field at two receiving antennas is very nearly equal to the direct response of one antenna to an impulse applied at the other one. Exploiting the diffuse wave field generated by rotation of a mechanical mode stirrer inside a reverberation chamber (RC) excited by a single transmitting antenna, we outline the convergence of the cross-correlation toward the impulse response between the two receiving antennas. The laboratory demonstration shows that it is possible to characterize passively the coupling between two antennas in an RC.
