DESIGN AND ANALYSIS OF AN INTERFERENCE GENERATION CIRCUIT FOR A HANDHELD UAV SUPPRESSION DEVICE

Tóm tắt

The rapid proliferation of unmanned aerial vehicles (UAVs) has introduced significant security challenges in both civilian and military environments. UAVs rely heavily on radio-frequency (RF) communication links for command, telemetry, video transmission, and satellite-based navigation (GNSS). Disrupting these RF links through intentional broadband interference represents a viable approach to degrade UAV operational capability. This paper presents a theoretical and simulation-based study of broadband interference generation for personal UAV suppression systems. The work focuses on signal modeling, performance metrics such as Jamming-to-Signal Ratio (JSR), Signal-to-Interference-plus-Noise Ratio (SINR), Carrier-to-Noise density ratio (C/N₀), and Bit Error Rate (BER). A multi-band interference generation framework is analyzed using system-level modeling and MATLAB simulations. Results demonstrate the quantitative relationship between interference bandwidth, power spectral density, and degradation of GNSS signal quality. The study provides a rigorous analytical foundation for evaluating interference-based UAV countermeasure systems in constrained portable platforms.
