摘　　要：针对捷联惯组误差系数对制导武器打击精度影响的差异,并结合实际样本数据为小样本的情况,提出了基于灰色关联判断矩阵的权重分析方法。利用灰色关联法分析计算捷联惯组误差系数与落点偏差的关联度,基于关联度确定矩阵元素,进而建立判断矩阵,最后应用归一化方法计算误差系数的权重。实例证明,灰色关联判断矩阵法能有效降低人为因素的影响,提高捷联惯组误差系数权重计算的精确度。Based on Gray Correlation Judgement matrix, a weight analysis method is presented for the different influence on the weapon＇s impact point, which is caused by each error coefficient of Strapdown Inertial Measurement Unit （SIMU）. Calculating gray correlation degrees of the error coefficients with the impact point by gray hierarchy analysis, judgement matrix is founded and weights of SIMU error coefficients are established. The practical calculation shows that this method can reduce the influence of humankind availably and improve the accuracy of weights of SIMU error coefficients.
