Abstract

Aiming at the basic practical problems such as the lack of quantitative technical indicators for the performance evaluation of existing digital equipment model validation methods, the absence of theoretical support for the adaptability analysis of methods, and the insufficient of technical support for the application of model validation results, this paper for the first time proposes and defines the concept and connotation of the model validation resolution(MVR) of digitize test model simulation validation methds, and proposes to use the model validation resolution as a performance indicator for evaluating model validation methods. A performance evaluation technology and adaptability analysis method for model validation methods based on the model validation resolution are established, and an operation process for selecting appropriate simulation model validation methods according to specific application backgrounds is determined, providing technical support for the targeted selection and application of digitized test simulation model validation methods. The calculation steps of the model validation resolution based on the Monte Carlo method are given, and the basic properties of the model validation resolution are proven. Through numerical tests and application examples of the model validation of the virtual-real hybrid simulation system of a laser beam riding guided anti-tank missile, the effectiveness and engineering application value of the methods in this paper are verified.
