Because of the relationship between diffusion field of electromagnetic wave in conductive medium and electromagnetic wave equation in lossless medium,transient electromagnetic(TEM) method pseudo-seismic technology can be realized and wavelet can be transformed accordingly. But the transformed virtual wave is often with wide waveform,which reduces the resolution and affects the development and promotion of pseudo-seismic method.In this paper,we studied waveform broadening phenomena of virtual wave.Firstly,we discussed the reasons for virtual waveform broadening phenomena,pointed out that it is not due to the energy loss when wave propagates in the medium,but because that the propagation velocity of virtual wave in the virtual medium is much smaller than the velocity of electromagnetic wave propagating in the physical medium.Secondly,we put forward an idea that uses deconvolution technology to eliminate the waveform broadening effect in the wave-field transformation.We also computed and processed several known models and achieved good results which proved that the TEM method pseudoseismic technology can enhance the capacity of TEM method to identify the underground electrical interface so that makes the transient electromagnetic method in fine exploration possible.
