According to the realistic requirement of CGF in the simulation training system, this paper has studied the operator's skills and established operation skill model which can reflect the true level of training. On the basis of the analysis of the relevant principles and laws of the skills, the method of time series analysis has been used in forecasting. This paper has used the exponential smoothing forecasting model and analyzed its principles, and has improved its defects in practical application. Finally, the usability and credibility of the model has been verified through two actual cases. The model has shown the operator's skills, and new ideas and methods of the study on the fidelity of CGF in the simulation training system has been provided.%针对模拟训练系统对CGF真实性的要求,从号手的操作技能入手,建立可以反映真实训练水平的号手操作技能模型,并在分析操作技能相关原理和规律的基础上,采用时间序列分析的方法对其进行预测.采用了指数平滑预测模型,详细分析了其原理,并针对其在实际应用中的缺陷进行了改进.最后,通过两个实际案例验证了模型的可用性和可信性.所建模型反映了号手的操作技能,为模拟训练系统中CGF的真实性研究提供新的思路和方法.
