Abstract

This paper presents a comparison between two different echo reduction techniques applied to one-single cut antenna measurements. These techniques are based on modal filtering and time filtering. The first technique uses a postprocessing of the far field one-single cut so as to obtain a modal expansion of cylindrical modes and to cancel the effect of spurious signals. The second one is based on filtering echoes out in time domain by applying a Fourier Transform to get a signal in which some spurious contributions can be filtered out. Such techniques are applied on the single cut measurements of a wideband horn (MVI SH2000) performed in a semi-anechoic chamber and on the measurements of a dipole (MVI SD1900) performed in a MVG spherical multi-probe system (StarLab). A smart combination of both methods is also applied in order to improve the results of the post processing with respect each different method.
