A General Method to Calculate the Source-Stirred Correlations in a Well-Stirred Reverberation Chamber

摘要

To identify the independent sample number in a platform-stirred reverberation chamber, the correlated angle of a rotating platform has to be identified. A general numerical method is proposed to calculate the farfield correlation in a source-stirred reverberation chamber. The proposed method is verified using a dipole antenna which has an analytical solution. General source antenna configurations are also investigated (e.g., a Vivaldi antenna) which show that the correlated angle is not sensitive to the radiation pattern of the source-stirred antenna for a large rotating radius.
