Design of Antenna Framework for a Larger Phased Array Radar

In recent years, the technology of large-scale phased array radar has been developed rapidly in China. As the structural carrier of antenna unit and a large number of electronic equipment, antenna framework has put forward high-quality requirements for its installation accuracy, array deformation, structural strength and other technical indicators. In this paper, taking the design of a large phased array radar antenna skeleton structure as an example, the related ideas and methods in structural design are described in detail. According to the structural layout of the antenna skeleton, the skeleton segmentation, assembly accuracy, connection strength and array accuracy are analyzed in detail to ensure the requirements of long-distance transportation, accuracy index and structural safety of the antenna skeleton. Finally, the design of antenna skeleton structure is verified by mechanical simulation, experimental measurement and theoretical analysis.
