摘　　要：提出了一种制导武器的命中精度评定方法:由大样本仿真试验仿真模型解出的均值和方差的置信区间可以用于小样本试验验收的标准,并通过实际试验数据验证了其正确性;针对不同的情况提出了两种直升机载稳瞄系统误差分析方法,即近似常值误差分析法和随机误差分析法,每一种分析方法都给出了解析解、数值解;最后给出了稳瞄系统照射精度的评定标准。An assessment method of guided weapon＇s impact accuracy was proposed. It is proven by flight-test that the expectation and variance results obtained from large-sample simulation model could be used as acceptance standard of small-sample test. Two kinds of helicopter-borne aiming error analysis methods, i.e. approximating constant error analysis method and random error analysis method, with respect to different cases were discussed. The assessment standard of illumination accuracy of aiming systems was proposed.
