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.
