基于多阶段试验信息融合的防空导弹飞行可靠性综合评估方法

针对防空导弹性能鉴定试验阶段导弹飞行可靠度评估试验子样不足问题,进行多阶段试验信息融合方法研究.综合分析性能鉴定试验前进行的飞行试验、导弹可靠性鉴定试验阶段的数据,得到可用于导弹飞行可靠度评估的子样数,结合性能鉴定试验中获取的子样数,运用二项分布经典评估方法对导弹飞行可靠度进行置信下限评估.评估结果表明:多阶段试验信息融合结果合理,在性能鉴定试验中具有较高的应用价值.

Flight Reliability Comprehensive Evaluation Method of Air Defense Missile Based onMultistage Testing Information Fusion

Aiming at the problem of insufficient sample in air defense missile reliability evaluation test during the performance qualification test, the multistage testing information fusion method was studied in this paper. By analyzing the experimental data of the flight test before the performance qualification test and the missile reliability qualification test stage, the number of missile samples for reliability evaluation was obtained. Combined with the number of samples obtained from the performance qualification test, the confidence limit of missile reliability was evaluated by classical binomial distribution evaluation method. The evaluation results show that the results of multistage testing information fusion are reasonable, and have high application value in the performance qualification test.
