Uncertainty Analysis of Spherical Near Field Antenna Measurement System at VHF

Technical Publications
11/14/2014

This paper presents parts of investigations done in a VHF spherical Near-Field system in order to estimate measurement uncertainties. First is briefly presented the monoprobe Near-Field system and uncertainties estimations challenges due to low frequencies. Then are described the specific and appropriated approaches for the considered errors terms. Classical pattern comparison is used.

Investigation of Echo Suppression Efficiency in Spacecraft Near Field Measurement Scenarios

Technical Publications

Measurement post-processing techniques based on spatial filtering have been presented as promising tools for the mitigation of echo’s deriving from the measurement environment in regular Near Field (NF) measurement scenarios [1]-[2].

Verification of Complex Excitation Coefficients from Measured Space Array Antenna by the Equivalent Current Technique

Technical Publications
