METHODOLOGY FOR SELECTING A COMPLEX OF ELECTROMAGNETIC METHODS OF SEARCH AND DETECTION OF EXPLOSIVE OBJECTS FOR THE STRUCTURAL SYNTHESIS OF THE SEARCH DEVICE

Abstract

The war of the russian federation against Ukraine led to the fact that our country became the most mined in the world. At the same time, in the confrontation, a constantly growing role of mine weapons is observed, the share of which in the fire damage of the enemy is constantly increasing. Also, there is a significant imbalance between the development of mine weapons and means of detection, which in turn causes a number of problematic issues during demining. It is noted that Ukraine, in connection with the aggression of the russian federation, in addition to the problem of demining the territory contaminated with explosive objects, the issue of reconnaissance of the area for the presence of mines and making passages in the mine-explosive barriers of the enemy during offensive operations has become acute. The paper analyzes the process of demining, determines the factors influencing it, gives the main unmasking factors of explosive objects, as well as the execution of tasks for demining the area. Taking into account these features, theoretical approaches to the detection and identification of explosive objects, which are based on various physical principles, are considered. It is shown that one of the ways to increase the efficiency of search and identification of explosive objects is the integration of several methods in one search device. Based on the analysis of theoretical approaches to the detection of explosive objects, the work proposes a methodology for choosing a set of electromagnetic methods for detecting explosive objects, which should be used together in one search device for a guaranteed search during combat demining with a minimum given probability of detecting explosive objects. The five most common electromagnetic methods for searching for explosive objects were chosen for the study: induction, radio wave, radar, nonlinear radar and optical. The paper shows that in order to ensure a minimum guaranteed level of detection of explosive objects and increase the efficiency of the process of detecting explosive objects, it is sufficient to use two methods, in particular, induction and radar.
