Lightweight Spoofing System for Navigation Deception of Non-cooperative UAVs

The rapid advancement of Unmanned Aerial Vehicle (UAV) technology has led to its increasingly widespread application in both military and civilian sectors. However, the security risks posed by non-cooperative drones have become increasingly prominent. Traditional interception methods, such as net capture and high-power signal suppression, are limited by factors including short effective range and high costs. This paper proposes a lightweight navigation jamming and spoofing system. By designing a highly integrated navigation receiver antenna, transmitting antenna, and jamming source host, the system supports flexible switching between three operational modes. This capability enables effective management and control of non-cooperative drones. Experimental results demonstrate that the system successfully achieves both static jamming and dynamic spoofing of target drones, significantly enhancing the precision and reliability of UAV countermeasures. The development of this system offers a novel approach for low-cost, high-efficiency drone countermeasures, showcasing significant potential for application.
