摘　　要：文章基于有限元的方法对X波段多普勒天气雷达的结构进行模态分析,通过对比3个指向的各阶振型的最大位移量,找到振型影响最大部位,确定影响X波段多普勒天气雷达天线结构的关键因素及其影响程度,为优化天线结构提供了有益的参考,并对进一步研究进行了展望。In this paper, Model analysis on the structure of X-band Doppler weather radar is studied by means of finite element method （FEM）. By comparing the maximum displacement of vibration modes in three directions, the great effect to which part of the system can be found. The key factor which influenced the structure of X-band Doppler weather radar and their influence extent are studied. The research result provided valuable reference to structure optimization of the antenna and further study is prospected.
