摘　　要：多管火箭落点分布是评估其射程和密集度等性能的基础,在深入分析多管火箭武器系统特点的基础上,根据多元正态分布理论,推导了多管火箭落点的分布模型,得到了多管火箭落点分布是中间高两边低的对称分布,但不完全属于正态分布的结论;可以用正态分布近似多管火箭落点的分布,给出了两种正态近似的方法:方差相等法和峰度相等法;研究了非满管密集度试验的方法,首次从数理统计角度证明了非满管替代满管进行密集度试验的可行性,通过模拟仿真和试验数据验证了结论的正确性。The distribution of Mutiple Launch Rocket （MLR） falling points is the base of its fire range and scatter evaluation. Based on characteristics analysis of MLR weapon system, according to the multielement normal distribution theory, the distribution model of MLR falling points was deduced. The distribution curve was acquired, the curve is higher at center than both sides and is symmetry, but it is not normal distribution. By use of approximate normal distribution, the two approximate methods were given, one is variance equivalent method and another is kurtosis equivalent method. The test method of non-full MLR firing was studied, and from the point of view of mathematic statistics, the feasibility of density test was proved by using non-full MLR firing in place of full MLR firing in the test. The correctness of conclusion was verified by simulation and test data.
