摘要
重力仪漂移系数对于观测数据的有效零漂改正,进而获得可靠重力观测数据具有重要意义。笔者提出利用模糊加权线性回归法进行重力仪漂移系数计算,通过对理论与实际的重力仪静态数据的试验、比较与分析,认为该方法具有计算自动化、有效压制干扰、计算结果稳定等特点,能够实现对重力仪漂移系数的有效计算,具有应用前景。
The zero-drift coefficient of gravimeter is of significance in the effective zero-drift correction of observation data and achieving reliable gravity data. The authors apply fuzzy weighted linear regression algorithm on the calculation of zero-drift coefficient. The results of trial,comparison and analysis based on the analog data and real data of gravimeter show that the algorithm is automatic calculation,can suppresse the noise effectively and get reliable calculating result,which can realize the effective calculation of the zero-drift coefficient and has future application potential.
