| 摘 要： | 探讨了在波数域作静效应校正的可能性,提出利用各频点互相关矩阵作为选择滤波截止波数的理论依据,并对三维数值模拟结果作了处理,表明在波数域消除静效应是可行的。最后,对云南某地的CSAMT数据作了试算,得出了较好的效果。

| Abstract: | Abstract The feasibility of making static effect correction in wavenumber domain is discussed
in this paper. The paper aug-gotta using the cross-correlation matrix as the theoretical basis for
choosing filtering cutoff wavenumber, and conducts data-processiai; for three-dimensional numerical
simulation. The results demonstrate the practicability of eliminating static effect in the wavenu-
mber domain. CSAMT data from a certain area of Yunnan Province were tenratively calculated,
which yielded fairly satisfactory results. |
