海洋磁力测量中异常数据探测方法研究

The abnormal data detecting methods in marine geomagnetic surveys

本文采用门限滤波法、滑动拟合法及其基于三维可视化的滑动拟合方法对海洋磁力测量地磁日变数据和海上磁测数据中的异常数据进行探测,并结合实际试验数据进行了详细比较分析,结果表明方法合理,该方法具有一定的实践理论意义。

The threshold filtering method, the glide filtering method and the gilding method which based on the three -dimensional visualization method has been used in the abnormal data detecting of the geomagnetic diurnal variation data and the magnetic data observed on the sea. The methods has been compared and analyzed with the observed data. The conclusion shows that the methods proposed in this paper can be applied in the abnormal data detecting in marine geomagnetic surveys.
