MARS Reflection Suppression Software

Far-Field Amplitude

MARS Correction Applied


Reflections in antenna test ranges can often be the largest source of measurement errors, dominating all other error sources. The MARS Reflection Suppression Software uses a new technique developed by NSI to suppress reflections from many sources in far-field ranges, and cylindrical & spherical 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. The technique is a general technique that can be applied to any spherical range. It has been used in a large hemispherical automotive antenna range implemented by NSI-MI for Nippon Antenna in Itzehoe Germany (link), as well as for many other customers. It has also been applied to extend the useful frequency range of microwave absorber in anechoic chambers.
