Abstract
In the current context of active electronic warfare and the growing need to secure the information space, efficient frequency resource management has become increasingly critical. The impact of electronic warfare (EW) systems on communication and data transmission channels significantly impairs the operation of both military and civilian communication systems. Therefore, the development of adaptive approaches to frequency spectrum allocation, capable of promptly responding to changes in the radio frequency environment, is of paramount importance.
This paper presents an original methodology for dynamic frequency resource management using Software Defined Radio (SDR) technologies. This approach enables real-time, flexible adjustment of radio system parameters, allowing for effective counteraction against interference and jamming threats. The methodology takes into account the intensity of radio interference, the spectral density of signals, the current state of the electromagnetic environment, and the ability to predict potential communication loss risks.
The study also discusses an algorithm for spectrum monitoring based on an SDR receiver, which facilitates rapid identification of high radio noise areas and quick reconfiguration of transmitters to less congested frequency bands. The architecture of the software-hardware system implementing this methodology is described. Special attention is given to automating the process of selecting the optimal frequency range using machine learning and artificial intelligence techniques. Simulation results confirm the feasibility and effectiveness of the proposed approach. The use of SDR technologies in dynamic frequency management significantly enhances the resilience and reliability of communication systems under electronic warfare conditions. The proposed solutions can be integrated into existing military and specialized communication management systems, as well as applied in the development of advanced telecommunications projects.
