Large-scale radar antenna pedestal structure system complexity,high cost,development cycle tension.How to ensure anten-na pedestal structural design a success to meet the radar structure technical requirements is antenna pedestal development of the prob-lem.In this paper,this combination of engineering research,from the antenna pedestal structure system mechanical design,computing modeling principle,modeling,bearing and other key parts of connection processing,simulation model simplify and equivalent,whether the oblique beam program simulation results compare and select,as well as track flatness,auxiliary support force determine to final structure optimization simplify were described for large-scale pedestal radar antenna structural design with some guidance.
