Spatial Autocovariances of Scattering Parameters in a Lossy Reverberation Chamber

Abstract
We derive a statistical model for the spatial autocovariance of two-port scattering parameters in a high-loss reverberation chamber for single-mode antennas. The theoretical model accounts for first- order antenna-antenna and antenna-environment interactions arising due to scattering off of the measurement antennas. The model is shown to provide a good description of the empirical spatial autocovariances calculated from scattering parameter measurements in a reverberation chamber for different loading configurations. This provides new insight into the complex antenna-antenna and antenna-environment interactions that occur in reverberation chamber measurements. Additional applications include reducing the correlation between reverberation chamber measurements obtained using position stirring and measuring the orientation-averaged total scattering cross-section of arbitrary structures.Citation
