| 摘 要： | 根据A.A.考夫曼推导水平层状介质表面上磁偶极子电磁场表达式的思路,推导出了水平层状大地上方磁偶极子电磁场的表达式,采用两层和三层典型层状大地模型,研究了不同飞行高度的电磁场响应特征。计算结果表明,飞行高度的变化直接影响测点的电磁响应大小。

| Abstract: | Based on the expression of ground layered media on the surface magnetic dipole field derived by A.A.Kaufman,the authors deduced frequency-domain airborne electromagnetic field’s expression for magnetic dipole source.Using two-layer and three-layer typical earth model,the authors studied electromagnetic response at different flying heights.Calculations show that the changes of the flying height affect directly the electromagnetic response’s value of points measured. |
