摘　　要：为了获取高精度弹道,针对各单台设备的定位数据,引入诱导有序加权算术平均算子,建立基于该算子的组合估计算法,并引入不同误差指标进行比对分析。计算表明,该方法确定的弹道明显优于各单项估计弹道,也好于加权算术平均算法计算的弹道。利用基于诱导有序加权算术平均算子的组合估计方法开拓了外弹道数据处理途径,有效提高了数据处理的精度。For acquiring high-precision location trajectory,based on location data of each of equipment,the concept of induced ordered weighted averaging（IOWA） operator was presented,and the combined evaluation algorithm based on IOWA operator was set up.The results evaluated by single-equipment location data were compared with the one calculated by weighted averaging operator,the trajectory based on IOWA operator had superior precision.It indicates that the combined estimation method based on IOWA operator extends the way to data processing of tracking measurement and effectively improves the precision of trajectory.
