Determination of the reverberation chamber stirrer uncorrelated positions by means of the spatial and frequency correlation matrix

The uncorrelated stirrer positions of a reverberation chamber are computed by means of Pearson's correlation matrix. Two methods are adopted to populate the matrix, and results are compared with those given by standard method. The former uses the total electric field magnitudes sampled in a large spatial lattice in the working volume for each stirrer position. The latter uses the same quantity sampled within a frequency band for a single point in the working volume for each stirrer position. Results returned by the two methods are compared for a large chamber equipped by a rotating carousel stirrer.
