Uncertainty analysis of microwave power measurement with Monte Carlo method

Abstract

Monte Carlo Method is a kind of statistic simulation method. Many complicated transform and nonlinear problems in mathematic model of metrology can be solved with Monte Carlo Method. So Monte Carlo Method is frequently used for uncertainty analysis in metrology recent years. As to measurement of microwave power, traditional uncertainty analysis ignores or over-estimates some uncertainty because the precise model of uncertainty is too complicated to use. This paper firstly tries to provide a perfect model of microwave power measurement uncertainty and then discusses uncertainty evaluation by Monte Carlo Method including mathematic modeling and Monte Carlo simulation. Analyzed results with Monte Carlo Method are also provided.
