Abstract

The article discusses the principles of processing recorded signals in local geoecological monitoring systems for the formation of phase images of geodynamic processes. The importance of continuous monitoring and control over the influence of geodynamic processes on natural resources and infrastructure engineering and technical objects in the process of their interaction is noted. It is shown that an effective option for local geoecological monitoring of these processes is the use of modern systems based on the use of geoelectric control methods, which are highly sensitive to changes in the electrical properties of the monitored objects. Along with the advantages of these methods, their disadvantages in controlling the amplitudes were noted, in particular, the complexity of solving monitoring problems in the presence of regular interference influences, changes in climatic factors and variations in the parameters of a specific measuring installation, in connection with which it is shown that the application of the method based on phase control is promising. higher sensitivity and noise immunity. A mathematical description of the phase–measuring method is given, structural diagrams and functional models are developed, which can be used for the practical implementation of measuring paths of systems for local geoecological monitoring of various geodynamic processes. The proposed approach was successfully experimentally tested in the process of studying a model of a phase–measuring measuring system for monitoring geodynamic karst processes in the coastal zone of Lake Svyato, Nizhny Novgorod region, which showed its high sensitivity to recording changes in phase images for extremely small geodynamic processes of natural and artificial origin.
