- Abstract
In order to improve the adaptability, safety and reliability of unmanned aerial vehicle (UAV) telemetry, tracking and control (TT&C) system in complex electromagnetic environment, and solve the problem of dynamic spectrum resource management faced by multi-stations and multi-UAVs working in the same space, a novel UAV TT&C system based on interference sensing and spectrum resource management technology is proposed. The system combines communication reconnaissance technology with cognitive radio spectrum sensing technology, provides full-band interference identification and dynamic spectrum resource management for uplink / downlink. A wireless test platform for interference sensing and spectrum resource management system is built. Performance test results show that when the interference signals exist in the uplink / downlink and the link quality is poor, the system can adjust the spectrum resource adaptively, avoid the influence of interference signals effectively, and improve the survivability and operational effectiveness of UAV TT&C system.
