Estimation for the Random Errors of Reflector Surfaces Using Measured Data

다국어 초록 (Multilingual Abstract)

In this research, a novel error-decomposition scheme is developed to determine efficiently the random errors of reflector surface basedon the discrete measurement data. The least squares fitting of semi-closed B-spline surface is employed. Subsequently, a spatialstatistical analysis is performed to determine whether the spatial independent distribution of the sampled data points is attained fora given confidence level. This research rests on the assumption that the measurement errors of instruments are trivial compared withrandom errors caused by machining and assembly inaccuracies. The presented methodology has been applied to the surface analysisof a 3.7 m reflector antenna.
