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.
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 -.
In this paper the inverse-source technique or source reconstruction technique has been applied as diagnostic tool to determine the complex excitation at sub array and single element level of a measured array antenna -.
Computational Electromagnetics (CEM) solvers are important engineering tools for supporting the evaluation and optimization of antenna placement on larger complex platforms. Due to the conclusiveness and high reliability of actual measured data, antenna measurements are required for the final validation of most systems containing an antenna.
