The Research On Civil Aviation Radio Monitoring Method And Technology Based On Spectral Sensing

With the rapid development of civil aviation industry at home and abroad,aviation security situation is more and more severe.However,due to aviation and radio monitoring is two different industries,and the current civil aviation radio interference more and more,leading to find interference information behind the investigation inefficient.And the current domestic ADS-B(secondary radar technology)is not perfect,radio monitoring site coverage has not been fully covered,resulting in aircraft flight safety is difficult to guarantee.Therefore,the combination of ADS-B technology and radio monitoring,the deployment of small sensor nodes,to achieve complete route radio monitoring is an important project to ensure aviation safety.ADS-B technology and civil aviation radio monitoring technology to carry out research,research and development of small-scale monitoring equipment and civil aviation radio monitoring system for field testing.It includes the construction of transmission networks,the design of sensor nodes,real-time display of flight trajectories and monitoring of the air band spectrum and other parts.This paper makes a brief analysis and research on the current development of civil aviation industry,the current situation of aviation safety and the current situation of civil aviation radio related technology at home and abroad.And then the theory of the relevant radio wave transmission research,planning and design of the deployment of the H90 route as an example of the sensor node.Selected the system engineering related equipment,and the parameters were described,choose to build a suitable system for the transmission network.Then the overall framework and function of the system engineering are analyzed and designed,and the sensor node and the convergence center database are designed.Finally,the monitoring system of civil aviation radio is completed,and the system function is improved.Through the combination of ADS-B technology and civil aviation radio monitoring technology,the corresponding monitoring system is developed,which effectively combines the flight path reconstruction and air band monitoring to realize the effective monitoring of air radio and the flight path Real-time monitoring.
