| 摘 要： | 通过对实际复杂地形条件下中心回线瞬变电磁测深观测场量的几何分析，提出了在简单斜坡地形条件下瞬变电磁资料的几何校正法。该方法对观测场量和反演深度2个参数进行了几何校正。通过实际资料的处理以及与地表地质结构的对比说明，该方法效果良好，可推广应用到较为复杂的地形条件下。

| Abstract: | Based on an analysis of the geometry of the observed fields from central loop transient electromagnetic sounding, this paper proposes a topographic correction method for TEM data acquired under the conditions of simple slope topography. This method can carry out geometric correction for the observed fields and inverted depth. Real data processing and comparison with near surface structure show that the method have yielded desired results, and may be generalized to more complex topography. |
