Рассмотрено влияние нестабильности амплитуды зондирующих импульсов тока на кривую становления поля при питании зондирующей установки от аккумуляторных батарей. Предлагается методика учета изменения тока в зондирующей рамке, позволившая дополнительно улучшить соотношение сигнал – помеха в получаемых кривых зондирования. На основе работ В.А. Сидорова и М.С. Жданова показаны варианты приближенного решения обратной задачи методом зондирования становлением поля в ближней зоне (ЗСБ), реализованные в программном обеспечении электроразведочного комплекса. Рассмотрен способ улучшения метода решения обратной задачи ЗСБ в рамках модели с проводящей S плоскостью, позволяющий повысить достоверность получаемых результатов.</p></abstract><trans-abstract xml:lang="en"><p>The article considers the methodology of obtaining geoelectric characteristics of the medium for the experimental electrical exploration complex with pseudonoise signals intended for studying modern geodynamic processes occurring in the lithosphere of the Northern Tien Shan, taking into account the features of its hardware and software implementation. The influence of instability of the amplitude of probing current pulses on the transient curve is considered when the probing setup is powered by batteries. A technique is proposed for accounting for changes in current in the probing frame, which allows for additional improvement of the signal-to-noise ratio in the obtained probing curves. Based on the works of V.A. Sidorov and M.S. Zhdanov, variants of an approximate solution to the inverse problem of Transient Electromagnetics Method (TEM) are shown, implemented in the software of the electrical exploration complex. A technique for improving the method for solving the inverse problem of TEM within the framework of a model with a conducting S plane is considered, which allows for increasing the reliability of the results.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электроразведка</kwd><kwd>шумоподобные сигналы</kwd><kwd>корреляционная обработка сигналов</kwd><kwd>метод&#13;
