摘　　要：现有天线曲面拟合算法均基于最小二乘法,难以消除多个粗差对拟合结果的影响。本文基于等价权抗差估计思想,利用线性规划计算残差初值,再进行选权迭代计算。通过算例,证明本文方法能较好地探查多个粗差,且计算结果精度更高。Existing antenna surface fitting algorithms are based on Least - squares algorithm, which are difficult to overcome the influence of fitting results by gross error. This paper uses linear programming to calculate residuals of initial, which is based on equivalent weight robust estimation, then select weight to calculate. The method can probe multiple gross errors by calculating example and calculation results is more accurate.
