MULTI-LEVEL INTEGRATION OF SENSOR AND EOBD SUBSYSTEMS IN PERIMETER SECURITY SYSTEMS

Abstract

The article considers the problem of increasing the effectiveness of perimeter security systems in the face of growing threats associated with the use of unmanned aerial vehicles. Traditional systems that use sensor surveillance networks or electronic warfare means separately often do not provide a sufficient level of detection accuracy, response efficiency and energy efficiency. In this regard, the paper proposes a concept for building an integrated multi-level system that combines sensor monitoring nodes, regional information processing controllers and a central control module for electronic suppression means.

A mathematical model of the functioning of such a system has been developed that describes the processes of signal formation at the sensor level, information aggregation at the regional level and decision-making on the activation of electronic warfare means at the central level. The model takes into account the probabilistic characteristics of object detection, mechanisms for collective processing of sensor data, assessment of the effectiveness of jamming of control channels of unmanned aerial vehicles, as well as optimization of the distribution of energy resources between jamming transmitters.

To verify the effectiveness of the proposed approach, a simulation of the operation of the perimeter security system was conducted at different intensities of the appearance of unmanned aerial vehicles in the controlled area. The results obtained showed that the use of multi-level integration of sensor and electronic warfare subsystems allows to increase the UAV blocking coefficient by approximately 15% compared to non-integrated systems. At the same time, a reduction in the integrated energy consumption of jamming devices by 8–10% is achieved due to the optimization of their activation modes.

The results obtained confirm the feasibility of using an integrated multi-level architecture to increase the reliability of protection of critical infrastructure and other objects from modern air threats.
