Aeronautic Air Traffic Control Radar Data Network Technology

The necessity and feasibility of aeronautic air traffic control radar data network of China is put forward, and the related key technical subjects are discussed. We stress on the selection of communication technologies, the selection of the modes of management, the structure design and the specification of the radar data network. All the discussion is based on the analytical results on the peculiarity of radar data communication and the situation of China, and refers to the experiences of other countries. The relationship between the radar data network and the ATN or IP network is also considered. Some of the above subjects are important common issues for kinds of national VPN and special networks, too.
