N2 - The correlation coefficient is of great significance to the antenna pattern reconstruction based on reverberation chamber (RC) measurements. The correlation coefficients between two antennas are determined by their electric fields, and the radiation components of the electric fields can be expanded into a summation of the spherical wave coefficients. In addition, the rotation pattern of the antenna to different angles can be obtained through the rotation matrix, and the correlation coefficients between the original pattern and the rotated one can also be expressed by the spherical wave coefficients. Therefore, the radiation pattern of the original antenna under test (AUT) can be reconstructed reversely by using the correlation coefficients and the rotated spherical wave coefficients. This method has been verified in a well-stirred RC. In this work, we investigate the performance of the method in an imperfect RC with a non-isotropic scattering environment.
