Assessing Risk Levels of Signal Simulation VV&A Based on Feature Matching

Abstract

This article presents a method for assessing risk levels of signal simulation verification, validation, and accredita-tion based on feature matching. To analyze quantitatively uniformity level between simulation signal and the real signal or what is expected, the concept of uniformity coefficient of simulation signal is given as well as its estimation method by parameter estimation. From the perspective of feature matching, the risk level of simulation signal is assessed by risk analysis of statistical inference, and a decision method for accrediting simulation signal based on risk assessment is presented. The method is applied in the simulation development of ship's radiated-noise, and the result shows that it is helpful to improve both developmental efficiency and decision level in signal simulation.
