Keywords: geoelectrical exploration, electromagnetic monitoring of the Earth’s crust, pseudonoise signals, correlation processing of signals
Аnnotation: The modern hardware and software of the technology of active electromagnetic monitoring of the Earth’s crust on the territory of the Bishkek geodynamic polygon, developed at the Scientific Station of the Rus- sian Academy of Sciences, is considered. A technique for obtaining time series of apparent electrical resistivity for characteristic points of the field formation curve is described. An experimental technology of active electromagnetic monitoring of the Earth’s crust using pseudonoise probing signals is presented. An experimental sample of an instrument-software measuring complex with pseudonoise signals is considered, the construction of which is based on the method of field formation in the near zone.
