METHOD OF FORMATION AND ALGORITHMS FOR PROCESSING PHASE-METRIC IMAGES IN PROBLEMS OF SPATIAL CONTROL OF GEOTECHNICAL OBJECTS

The article is devoted to the solution of the problem of increasing the efficiency of geodynamic monitoring of extended objects (main pipelines, perimeters of protected areas) using automated phase measurement systems. The limitations of traditional measuring installations (the “two components” method, radial) for such objects are analyzed. A new configuration of the placement of point poles-sources and receivers of the “braid” type is proposed, providing optimal coverage of the control zone. A method for spatial location of anomalous geodynamic processes based on the analysis of the vector of changes in phase signals has been developed and tested. To improve the accuracy of localization in conditions of high geodynamic activity, a modification of the algorithm is proposed using weighted numerical values of exceeding detection thresholds. The results of laboratory and field experiments confirm the effectiveness of the proposed solutions for accurate detection and localization of disturbances in the near-surface part of the geological environment.
