Abstract. The article presents the development of a new electric exploration measuring complex with pseudonoise sounding signals. The complex is designed for sounding the Earth's crust using the transient electromagnetic methods. The technical characteristics of the complex and the results of the first field experiments carried out on the territory of the Bishkek geodynamic polygon are presented. The tasks are set to improve the technical and operational characteristics of the complex, the implementation of which will allow using the developed measuring complex to improve the technology of electromagnetic monitoring of the earth's crust, carried out at the Research Station of the Russian Academy of Sciences.

Keywords: geoelectrical exploration, electromagnetic monitoring of the Earth's crust, pseudonoise signals, correlation processing of signals, structural disturbances
