Abstract
An electromagnetic equipment operating in frequency domain was developed to prospect shallow conductive targets, as found in hydrogeological and archaeological surveys. Using low magnetic induction number concepts and lock-in circuits, it became possible to characterize conductors and ferromagnetics materials buried in subsurface, using the dipole electromagnetic profiling method.
