Abstract

The regularities of the amplitudes and phases connections of MT-impedance tensor components for 2D geoelectrical synthetic models have been considered. The amplitude-phase correction (APC) allows to improve the quality of data processing results both for the main and for the additional impedances. It also gives a possibility to suppress biased data for noise pollution data. Recommendations on accuracy rising of determination of tensor impedance components in the MT-data processing have been defined on the base of found regularities.
