Abstract: With the widespread application of drones in the low altitude field, establishing an efficient and safe low altitude drone traffic management system has become an urgent need. This article explores the application of radio spectrum sensing technology in low-altitude unmanned aerial vehicle traffic management. It deeply analyzes the performance characteristics of existing spectrum sensing methods and their application scenarios in unmanned aerial vehicle recognition, positioning and tracking, communication security, and collision avoidance. A low altitude unmanned aerial vehicle traffic management architecture based on spectrum sensing is proposed, and corresponding solutions are proposed for key technical challenges. Radio spectrum sensing technology can effectively enhance the monitoring capability of low-altitude unmanned aerial vehicles and provide key technical support for building a safe and reliable low-altitude unmanned aerial vehicle traffic management system.
