为进行远程多管火箭系统( LRMLRS)射击精度试验评估,提出了一种计算和评估方法。分别对考虑系统偏差和不考虑系统偏差时的LRMLRS射击精度进行了描述,形成了相应的计算方法。通过概率积分变换,转化了射击精度的描述方法。提出用传统的射击密集度评估方法即可进行射击精度评估的新思路,以目标点表征的系统均方差为σ′,系统射击精度R是否满足射击精度指标R0的检验可转化为σ′对应的R是否满足R0的检验；以目标点表征非满管射击系统的系统均方差为σ′1,满管射击系统的系统均方差为σ′2,非满管射击系统与满管射击系统射击精度是否相等的检验可转化为σ′1对应精度R1与σ′2对应射击精度R2的检验；用χ2检验对射击精度是否满足指标进行检验。在工程实际应用中,在减少试验用弹量58%的基础上,实现了对射击精度的评定。

In order to evaluate the firing precision of long range multiple launch rocket systems ( LRMLRS) ,a calculation and evaluation method of firing precision is proposed. The firing precision of LRMLRS with and without considering the system deviation is described distinguishly, and a calculation method is presented. The describition method of firing precision is transformed using the probability integral transition method. The firing precision can be evaluted using the tranditional evaluation method for firing dispersion. The mean square deviationσ′is characteriszed by the object points,the test of whether the system firing precision R satisfies the firing precision index R0 is transformed into the test of whether R corresponding toσ′satisfies R0 . The mean square deviation of a non-full loading firing systemσ′1 and the mean square deviation of a full loading firing systemσ′2 are characteriszed by the object points,the test of whether the firing precision of the two systems is equal is transformed into the test of R1 corresponding to σ′1 and R2 corresponding to σ′2 . The χ2 test can be used for testing whether the firing precision satisfies the index. In practical engineering, the evaluation of firing precision is realized,and experimental rockets are decreased by 58%.
