Extending cylindrical mathematical absorber reflection suppression to further reduce range scattering errors

Recent work in developing a mode orthogonalisation and filtering post processing algorithm for multipath suppression in far-field and planar near-field antenna measurement systems has enabled worthwhile improvements to be obtained from the analogous, but mathematically and computationally distinct, cylindrical analogue. This paper presents an overview of the measurement and novel post-processing algorithm as embodied within the cylindrical mathematical absorber reflection suppression technique as well as comparing and contrasting results obtained from the new post-processing algorithms with previously published data.
