Abstract
This paper proposes an improvement for the standard algorithms used to correlate the radiated emission measurements performed in a gigahertz transverse electromagnetic (GTEM) cell to measurements performed at an open area test site (OATS). The improvement compared with standard correlation algorithms lies in the ability to use literally all data measured. This is achieved by using nonlinear regression models in order to estimate the amplitudes of a multipole model. Assuming equally phased dipole moments and using nine measurements, numerical simulations indicate significant superiority of this new algorithm in comparison to the standard approach. The results can be improved further by using additional measurements. The simulation results show strong evidence that the algorithm also provides precise results for the amplitudes, if not all components of the dipole moments are in phase. Experiments with a real-world test object further validate the method.
