Unmanned Aerial Vehicle Anti-collision Technology Research In Control Airspace

The great potential of Unmanned Aerial Vehicle(UAV)application in military,civil and public fields has been proved again and again.The key impediment to its development is the operations of UAV in air traffic management(ATM)control airspace.The most effective way to solve this problem is the research of UAV integration into ATM control airspace with ATM separation to realize shared airspace among conventional aircrafts.The research of UAV anti-collision in ATM airspace is almost blank.Based on the classification of UAV available level,this paper sets up a common classification link between UAV and traditional aircraft,and puts forward the key constraint conditions for the UAV to enter the shared space.Establish the ris`k model of UAV and traditional collision and carry out the risk assessment of UAV control separation.Considering the performance characteristics of UAV and the requirements of airborne equipment,the risk values of UAV and traditional aircraft safety separation is derived from the UAV airborne and ground control as well as the external environment,considering the UAV control delay.By using the improved collision risk EVENT model based on ADS-B,the risk assessment of the collision avoidance separation of UAV in different airspace is carried out,which provides a feasible method to deduce and verify the collision avoidance interval of UAV in shared control area.
