摘要
为提高海洋磁力测量磁异常图的精度,提出采用检查线中点评估磁异常插值残差精度的新方法,并建立了与测线间距的关系。结果表明:检查线中点评估法充分利用了检查线上的磁测信息,更能真实地反映测线间磁异常的插值能力,且磁异常插值残差精度随着测线间距的增加而降低。
In order to improve the accuracy of magnetic diagram from marine magnitic surveying the evaluation method of the interpolation residual accuracy with midpoint of the cross-check lines was brought forward, and the relation between the interpolation residual accuracy and line spacing was analyzed. The study shows that the method can make full use of information along the check lines, the interpolation ability between the lines can be really re- flected but the interpolation residual accuracy will reduce with the increase of the line spacing.
