Abstract
Summary
This paper reviews improving of informativeness of shallow TEM by reducing the starting depth of sounding. Some estimation of efficiency has been performed between the “traditional approach”, based on damping of TX loop and an approach, based on additional low-pass filtering of TEM response in order to suppress parasitic oscillation process. In accordance to the results of mathematical modeling shown that influence of low-pass filtering should be taken into account during solving of direct problem in order to reach maximum accuracy and reliability of the inversion results. The new integrated software for the processing and inversion has been presented.
