| 针对声震波技术测量落点坐标过程中的粗差对计算结果的影响,提出了一种粗差探测方法和稳健估计下的声源定位最小二乘算法。该算法按照逐次迭代平差的方法,不断地改变观测值的权,使粗差观测值的权趋于零,从而降低粗差的影响。通过算例的比较结果表明：新算法的解算精度优于传统最小二乘算法,并且鲁棒性更强。 |
| 英文摘要: |
| According to the influence of the gross error on the results of seismic-acoustic wave detection method measurement in impact point coordinates, a gross error detection method and least square algorithm based on robust estimation was proposed. The method of successive iteration adjustment is used to continuously change the weight of the observation value, so that the weight of the gross observation value is zero, so that the influence of the gross error is reduced. The comparison results show that the new algorithm is better than the traditional least square algorithm, and the algorithm is more robust. |
