摘　　要：范数加权几何平均组合估计是一种非线性组合估计方法,可以通过不同跟踪设备测量数据的互补与冗余来提高飞行目标的定位质量。在外弹道数据处理中,根据给出的合理权值匹配准则对目标参数进行计算,其结果表明,该方法明显提高了测量信息的可信度并降低了信息的模糊度,减低了目标的不确定性,有效提高了飞行目标弹道参数的数据处理精度。The weighted geometric average combination estimation of norm is a kind of nonlinear combination estimations, which can improve orientation quality of target tracking by using the complementary and redundancy information of different tracking equipments. In exterior ballistics data processing, target parameters are calculated on the basis of the given reasonable weights matching criterion. The result shows that this method can evidently enhance the reliability of measurement information while decreasing the vagueness of the information, reduce the uncertainty of target, effectively improve the data processing accuracy on flying target＇s ballistics parameters.
