Abstract
There is a mathematical relationship between the transient electromagnetic diffusion equation in electric media and the wave equation. Thus, pseudo-seismic migration imaging is possible. However, the pseudo-seismic wavelets associated with the transformed data show a broaden waveform for increasing physical times. This phenomenon causes the resolution of the subsurface image to degrade and consequently limit the arrears of application for the Transient Electromagnetic Method (TEM). Horizontal resolution can be improved, certainly, through the technique of synthetic aperture algorithm. We developed a TEM pulse compression technique based on previous research in order to improve the vertical resolution. The result of synthetic model shows that the vertical resolution is improved after processing the synthetic aperture data with the pulse compression technique.
