Title weak correlation analysis of shooting errors
Abstract
The concept and classification of shooting errors were introduced. Three decomposition methods of weak correlated shooting errors were summarized. Existing algorithms of damage probability under the weak correlated errors decomposition were introduced. However, these decomposition principles cannot prove that the damage probability is constant after error decomposition. Therefore, a new algorithm of damage probability was proposed. The stationary normal miss-distance sequence was separated into common and uncommon parts; furthermore, the common parts were decomposed into prediction values and prediction errors. Based on above decompositions, the expression of damage probability of one shooting was proposed for the known initial values of the strong and weak correlated errors; then the expression of damage probability of the weapon systems was derived. Compared to the known results including those listed in the GJB(national military standards) by several examples, the accuracy of the algorithms given in this paper is better.

1.1 课题研究背景及意义
二战结束以来,新的世界大战没有发生,但局部战争和军事冲突却此伏彼起,一直没有停息过。决定战争的胜负因素是多种多样的。战争,首先是战略,而后是战役组织,其后是战术,一环紧扣一环。无论哪一环出了问题,都会对战争的结果产生影响。而武器系统,就是战术层面上的一个重要部分。即使我们身处和平年代,我们也深知国防对于国家和人民的重要意义。国防建设离不开先进的武器系统的支持。所以,对于武器系统的研究,具有十分重要的意义。
在战斗中武器系统的任务,都是通过“射击”来完成。而军事技术运筹学或兵器系统工程学的一个基本问题,就是评价与检验武器系统的射击效力。
本文基于此来研究射击误差的弱相关性分析,利用概率统计的知识,利用射击误差的分布求取命中概率;分析弱相关误差对命中率和毁伤率的影响,并与三种将弱相关误差强行分解为强相关和不相关误差的结果对比,完成MATLAB的数值仿真。 射击误差的弱相关性分析+文献综述:http://www.751com.cn/zidonghua/lunwen_6465.html
