【摘要】 根据不同组数据求取多管火箭落点密度函数。为克服不同组数据间的系统误差,采取位置平移方法。采用该方法要满足的两个条件是:每组中发与发之间相互独立;各组的试验条件要保持一致。根据多年试验数据分析了多管火箭A、B、C、D4种非满管射击方式和满管齐射落点分布的特点,进行的正态性检验和密集度对比分析表明:多管火箭落点纵向不完全服从正态分布,横向基本服从正态分布。采用A、B两种射击方式联合使用效果较好。更多还原

【Abstract】 Density function of multiple launcher rocket was solved according to data in different groups. To overcome system error between data and data in different groups, position translation method was used. Two conditions that using this method must satisfy are: a variety of rounds and rounds in each group are independent each other; test condition of each group must keep consistency. Features of multiple launcher rocket A,B,C,D firing modes are analyzed according to test data for many years. Normal examination and density comparison analysis showed that multiple launcher rocket longitudinal impact points do not completely conform to normal distribution, and lateral impact points basically conform to normal distribution. Operational effect of two firing modes such as A,B are better.更多还原
