Abstract
It is shown that in the AEM surveys the measurement of signals with two spaced in height receivers significantly reduces the equivalence of the solution and allows to separate the induction and polarizing components of the measured signal much more confident. In the absence of obvious signs of polarization its presence can only be determined with the use of dual measurements, otherwise the signals will be wrongly interpreted. Interpretation technology, based on the separation of the polarization and induction components of the measured signal with the subsequent 3D inversion in EM-Dataprocessor software allows to significantly increase the accuracy of the interpretation and increase the probability of target objects detecting. The results of experimental AEM research using VTEM and “Impuls-A-7” systems are presented.
