综合评估与假设检验相结合的飞行器性能评定方法

Performance Assessment of Flight Vehicle Based on Comprehensive Evaluation and Hypothesis Test

针对综合评估方法无法对飞行器性能给出明确结论的问题,论文提出了一种综合评估与假设检验相结合的飞行器性能评定方法。结合两种方法优点,利用综合评估方法中的指标体系、权重计算等手段从大量试验数据中挖掘有用信息,结合二项分布经典假设检验方法分析其内在的统计规律特性,达到系统性能评定的目的。将该方法应用到某型飞行器制导系统性能评定,结果与制导系统实际工作情况相符,方法的有效性得到了验证。论文提出的方法能够为飞行器设计、试验鉴定等领域提供有益参考。

The comprehensive evaluation can't give a clear conclusion of the performance of flight vehicle.Therefore,a perfor⁃mance assessment method of flight vehicle based on comprehensive evaluation and hypothesis test is proposed in this paper.Mining useful information from lots of test data by comprehensive evaluation and analyzing the inherent statistical law of information by hy⁃pothesis test,the advantage of two methods are fully exploited.By the performance assessment of flight vehicle guidance system,the validity of the method is verified.The method in this paper can provide good references to the design and test qualification of flight vehicle.
