In view of airtoground quantum communication of the AEW platform, in this paper, the main factors influencing transmission channel are analyzed. On the basis, a process of airtoground quantum is constructed to facilitate twoway pointing and tracking, and then to fulfill the transmission of quantum bits. A quantum widearea network can be established based on this communication process, which is composed of multiple airplatforms, ground stations and etc. Three kinds of routing strategies are proposed, and then analyzed based on the different communication nodes, and its feasibility is verified. Finally, the quantum bit error rate of the transmission is analyzed. The simulation results show that the improvement of channel coefficient, the reduction in the deviation angle of measurement based, error caused by entanglement swapping and classical information can result in a decrease of the transmission error rate.
