| 摘 要： | 为了解观测面以下位场场源体产生的异常，设计了一种波数域的滤波器，该滤波器可在无需岩石物性资料的前提下用于位场数据的反演．对位场资料用解析法和差分法上、下延拓，以消除浅表干扰源的影响，并最后下延至观测面以下，根据下延后场的极值确定场源的质心深度．理论模型的试算和实际资料的处理均获得了令人满意的效果．

| Abstract: | A wavenumber domain filter is designed to obtain potential anomalies beneath theobserving surface due to deep sources. The filter can be used for the inversion of thepotential field data without the knowledge of the Physical properties of the rock. Thistechnique requires to continue the potential data upward and downward several binesusing analyhc method and differenhal method in order to eliminate the shallowdistufbance and finally continue the data downward to a depth beneath the observingsurface. The mass center depth of a source is idenhfied based on the maximtun andminimum values of downward continuation potential data. The results based onsynthetic modelling and computing of real data of somewhere are satisfactory. |
