Study of the influence of mechanical errors in diagnostics applications by means of statistical analysis

Mechanical errors introduced by a planar measurement range and their effect on diagnostics applications are analyzed in this contribution. The study is based on Monte Carlo statistical analysis by means of an error simulation tool for antenna measurements and diagnostics applications. The effect of each type of error and its contribution to the final uncertainty of the system can be used to establish the error bounds and tolerance of the measurement system to mechanical inaccuracies for the implemented setups. Measurement and diagnostics of a W-band horn antenna with partial aperture blockage is considered for experimental testing.
