摘要
A new method based on cross-spectrum estimation for the verification and validation of computer simulation models is expounded in accordance with the characteristics of missile systems. The new method can expose the differences between two time processes in several aspects and can also give quantitative analysis results about the statistical consistence between them. An application to an actual anti-tank missile system simulation is presented and the calculated results confirm the effectiveness of the method. The approach can also be employed to verify the simulation models of other dynamic systems.
结合反坦克导弹系统的特点，提出一种基于互谱估计的检验导弹系统仿真模型有效性的新方法．这一方法可以从多个侧面反映两组动态数据之间的异同，并且可以给出二者之间统计一致性的定量估计结果．利用该法对某一实际导弹的数学仿真模型进行了检验，计算结果表明这一方法用于导弹系统仿真模型的验证是十分有效的；也可用于其他动态系统仿真模型的校核．
