Research on Assembly and Process Technique of Large Antenna Pedestal with High Accuracy

The large antenna pedestal with high accuracy is an important part of the large X-band phased array radar. It is characterized by large size, heavy weight and high accuracy. Besides, the assembly technique of the antenna pedestal is both important and difficult in overall assembly. In this paper, the assembly characteristic of the large antenna pedestal with high accuracy is analyzed. The postload deformation and its effect on assembly quality of the antenna pedestal are discussed. The measuring method of the postload deformation is put forward. And the assembly technique of the large antenna pedestal with high accuracy is introduced. Thus the difficult assembly problems of the large antenna pedestal with high accuracy are solved.
