Transform from transient electro-magnetic (TEM) electric section into pseudo-seismic section.

Xue Guoqiang , School of Electronic and Informational Engineering, Xi'an Jiaotong University, Xi'an City,Shanxi Province,710049,China Li Xiu  
In order to realize accurate interpretation of TEM sounding data, the idea of pseudo-seismic section transformation for TEM data produced by loop-source had been presented in the paper. The mathematical model was given in a condition of horizontal layered medium, the transform method and processing procedure have been put forward the secondary induced voltage data measured in field,after Fourier transform,was used to compute the wave-impedance by using linear numeric filtering in frequency domain;then after inverse Fourier transform,the reflection coefficient sequence qm of TEM field has been computed by linear programming in time-domain, and finally the pseudo-seismic section has been plotted by parameter qm. The results showed that the method is effective .
