MARS Correction Applied
Reflections in antenna test ranges can often be the largest source of measurement error, dominating all other
errors. The MARS reflection suppression software uses a new technique developed by NSI-MI to suppress
reflections from many sources in far-field and near-field antenna test ranges. The technique, named Mathematical
Absorber Reflection Suppression (MARS), is a post-processing technique that involves analysis of the measured data
and a special filtering process to suppress the undesirable scattered signals. This technique can be applied to any
range and has also been applied to extend the useful frequency range of microwave absorber in anechoic chambers.
