DEVELOPMENT OF EXPERIMENTAL RESEARCH METHODS FOR VERIFYING THE RELIABILITY OF MATHEMATICAL MODELS FOR THE DETECTION OF UNMANNED AIRCRAFT
Abstract
The work is devoted to the solution of an actual scientific task in the field of civil protection, namely, the formation of experimental research methods for verifying the reliability of mathematical models for the prevention of emergency situations of a terrorist nature at the objects of the critical infrastructure of Ukraine, which are protected, by means of timely detection and identification of small unmanned aerial vehicles by active optoelectronic means .
Based on the analysis, it was established that one of the trends in the development of terrorist scenarios at protected critical infrastructure facilities is the use of various small manned and unmanned aerial vehicles to carry out terrorist acts.
This work is a continuation of the cycle of previous works on the development of a structural and logical management model of an organizational and technical nature that ensures the safety of the protected object in the event of the appearance of small air targets. The developed method of experimental research to verify the reliability of mathematical models for detecting signals reflected from an emergency situation of a terrorist nature at a protected critical infrastructure object of Ukraine allowed to determine the following – the results of all field experiments performed using a laboratory installation, and theoretically calculated values of expected activities detection of targets as part of numerous experiments are located within the confidence intervals calculated according to the Student's criterion with a reliability of 0.99, which indicates a good convergence of experimental results and theoretical calculations. This, in turn, confirms the reliability of the mathematical model for detecting signals reflected from small unmanned aerial vehicles using active optical systems that use the phenomena of light absorption and scattering in optically transparent media and the mathematical model for detecting and identifying small unmanned aerial vehicles using passive optoelectronic systems.
