Investigation of Echo Suppression Efficiency in Spacecraft Near Field Measurement Scenarios

This paper presents the preliminary finding of the MV-Echo post processing validation for PNF measurements in the hybrid range. The GALILEO array antenna has been measured in different configurations and results with and without echo reduction processing are compared. The purpose of the activity was to quantify the benefits of the MV-Echo processing in a real case. Since the array is working in circular polarization it was possible to identify the major echo contributions as 2nd order reflections.
