对大地电磁测深(MT)资料,计算其变差函数;对这些变差函数进行回归分析,求得理论模拟变差函数;然后用泛克里格法估计大地电磁场信号,达到消除电磁场信号噪音的目的。

Varied difference function is calculated for MT data. And then we simulate these varied difference function, obtaining theoretical varied difference function. Finally the useful MT data is estimated with a Krige method. Through doing that, we get better result.
