      <abstract xml:lang="ru">
        <p>Рассмотрены связи между амплитудой и фазой всех компонент тензора магнитотеллурического (МТ) импеданса для 1D-, 2D- и 3D-теоретических геоэлектрических моделей. Выявлены некоторые общие закономерности этих связей, позволяющие использовать амплитудно-фазовую коррекцию для подавления смещенных оценок в зашумленных данных. На основе найденных закономерностей сформулированы методические рекомендации по повышению точности определения компонент тензора импеданса в процессе обработки практических МТ-данных. Рассмотрены примеры обработки полевых материалов МТЗ, полученных с использованием аппаратуры MTU компании «Phoenix Geophysics Ltd» (Канада).</p>

      <abstract xml:lang="en">
        <p>The regularities of the amplitudes and phases connections of magnitotelluric (MT) impedance tensor components for 1D, 2D and 3D geoelectrical synthetic models have been considered. The amplitude-phase correction 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. Examples of processing of field MT-data received on the basis of MTU equipment by «Phoenix Geophysics Ltd» (Canada) have been considered.</p>
