Missile System Simulation Model Validation Study

Credibility of modeling and simulation (M&S) is an important part of system simulation theory and it has been becoming indispensable to modern weapon system. Its core is the Verification, Validation and Accreditation (VV&A).This paper consists of two parts that it researches on the conception and technological methods of that VV&A for the missile system simulation. In the first part, the important conception, principle and correlative contents are narrated, and that validation methods of simulation test results are reasonably classified. In the second part, the main text of this paper discusses the quantitative validation methods while analyzes varied technology approaches and their feasibility of the static and dynamic consistency test. Firstly, statistical approaches are used to makes an intensive study of the static consistency in small-sample circumstances. Meanwhile Bayes theory is applied to the VV&A. And then, to validate consistency of two time series, AR model is deeply researched besides methods of various error norms. In the end, spectrum (classical spectrum and maximum entropy spectrum) comparative methods of dynamic consistency validation are discussed, including compare and estimation of stable series spectrum.In a word, this paper bases on engineering practice of missile system simulation, so it is hoped to direct engineering practice and further research.
