摘要 比较研究了卫星重力梯度数据粗差探测的阈值法、Grubbs检验、Dixon检验和小波分析法及组合方法。基于卫星重力梯度测量粗差的来源和特征,模拟生成了重力梯度数据的粗差,利用上述粗差探测方法模拟计算的结果表明:联合Dixon检验和小波分析的组合法最有效。 The outlier detection methods in satellite gravity gradiometry including threshold method,Grubbs’s test,Dixon test,wavelet method and combined method are studied.On the basis of the the origin and properties of satellite gravity gradiometry outliers,the gravity gradiometry dataset with outlier are simulated.The results indicate the combination of Dixon test and wavelet method is the most efficient algorithm.
