| 摘 要： | 逆散射反演是由已知散射波场反演地下介质中散射体各参数了分布的方法,本文从这一思想出发,针对二维大地电磁资料,在BORN近似的前提下,提出了一种新的反地下电导率参数的方法,经模型试算与实际资料的反演验证正确,这一方法特别适于地下无强电性分界面的地区。

| Abstract: | A new method of the conductivity inversion based on the electromagnetic reverse scattering is developed. This method is intended for processing and interpreting 2 D MT data. This idea is particularly suite to TE excitation. It can provide a good conductivity distribution map in the zone which has no interface with high conductivity ratio. It has gone through theoretical and practical examination and the result is correct. |
