Elektro- und Informationstechnik Generalised Test-Zone Field Compensation - Thomas Gemmer Kartoniert (TB)

An accurate echo cancellation technique not only reduces the cost but also the complexity of antenna measurement facilities as the performance of the absorbers and the alignment of the structures are not crucial anymore. Thus this thesis aims to develop an exact method based on the spherical wave expansion capable of compensating for undesired signals of arbitrary nature. To validate the theory a reflective environment is created and it is shown that the stray signals are corrected accurately.
