Abstract: How to improve the mobility of the mobile air traffic control radar is the important and difficult points in the mobile air traffic control radar design. This paper discusses some key technologies and their implementation methods，summarizes the structure design for the mobile air traffic control radar and puts forward the new folding method for antenna feeder resource. The folding method for parabolic antenna, lifting method and automatic leveling technology for the intelligent radar are applied to the air traffic control radar. As a result, the mobility of mobile air traffic control radar is greatly improved. Meanwhile, the telecommunication performance is ensured. Some notes and important points in the design are also given. This can be used as a reference for the same kind of product design.
