INTEGRATION OF SDR INTO UAV SYSTEMS

The article presents an in-depth examination of how Software-Defined Radio (SDR) technology can be integrated into Unmanned Aerial Vehicle (UAV) systems to enhance communication reliability, adaptability, and security. The aim of the article is to demonstrate how SDR-based architectures address critical challenges such as non-stationary channels, intentional jamming, and signal spoofing by enabling real-time reconfiguration and dynamic frequency management. The flexible nature of SDR allows UAVs to rapidly modify transmission parameters, apply robust coding techniques, and switch among multiple channels to maintain resilient links. The results obtained: case studies and experimental data indicate that SDR-equipped UAVs significantly improve situational awareness and mission survivability. Through continuous spectrum monitoring and advanced error-correction methods, these platforms can swiftly detect and mitigate interference or jamming attempts. Moreover, the integration of machine learning algorithms further refines threat classification, facilitating accurate identification of barrage jamming, GPS spoofing, and other radio-based attacks. Conclusions: adopting SDR in UAV systems not only strengthens communication links but also promotes scalability and cost-effectiveness by reducing hardware dependencies. This reconfigurability, combined with AI-driven signal analysis, positions SDR-enabled UAVs as a robust solution for diverse civilian, commercial, and defense applications under evolving radio frequency threats
