| 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. |
