摘要
结合某型导弹六自由度弹道仿真，将极大似然法作为弹道重构的主要手段，详细讨论了用于仿真验证过程的弹道重构方法和步骤，并给出了弹道重构的计算模型。以赛氏系数为性能指标，给出了一种模型验证的定量方法。这里特别强调用于弹道重构的数据应具有独立性。仿真结果表明，利用弹道重构对导弹六自由度弹道仿真模型进行验证是有效的。
Validation of simulation model is the essential links for the process of simulation. With six degrees of freedom trajectory simulation, a method of trajectory reconstruction by means of maximum likelihood method used in model validation is discussed in detail. Numerical calculation model of trajectory reconstruction is given. By taking Theil coefficient as performance index, a quantitative analysis method is provided. This paper emphatically points out independence of test data used in trajectory reconstruction.
