弹道修正弹系统效能灵敏度分析

Sensitivity Analysis of System Effectiveness of Trajectory Correction Projectiles

灵敏度分析是武器系统效能分析中的一项重要内容,针对正交试验的不足,在分析了弹道修正弹系统效能的影响因素的基础上,建立了基于均匀设计的弹道修正弹系统效能的回归模型。通过对模型求导得到了命中概率对各参数的灵敏度表达式,并进行优化分析,得到了系统效能参数的最优组合以及最优区间,研究结果可作为弹道修正弹参数优化设计的依据。

Sensitivity analysis is an important part of effectiveness analysis of weapon system. Against the deficiency of orthogonal test, a regression model of system effectiveness was built with uniform design, which is on the basis of analyzing the factors that influence on the system effectiveness. This paper gets the sensitivity expression by taking the derivative of hit probability model. By the optimization mean with computer, the optimal parameter combination and optimal parameter range are acquired. The obtained resuhs are practical to the parameter optimization design of trajectory correction projectiles.
