Multipole Parameters Out of Measurements: Uncertainty Considerations

摘要

A measurement method for a multipole approximation of arbitrary electromagnetic sources is motivated and described. In order to analyze the influences of different error sources, a method for the comparison of radiation patterns is introduced and the one dimensional correlation coefficient is identified as a quality factor for the similarity of radiation patterns. The quality factor is used for the analysis of different sources of errors, which can occur in. measurements. The paper shows, that one of the main influences on multipole approximations are reflections.
