摘　　要：针对天线阵面树形结构和故障组件分布对系统可靠性的影响,结合应用实例论述了复杂雷达天线阵面可靠性预计的方法。通过分析复杂雷达天线组成和功能的特点,考虑组件分布对系统可靠性的影响,建立了树形结构的可靠性框图,以Monte-Carlo方法开展了天线阵面平均严重故障间隔时间(MTBCF)的预计,并与传统可靠性预计方法进行了比较,得到了较为精确的可靠性预计结果。According to the influence of tree structure of antenna array and fault component distribution on system reliability,this paper demonstrates the method of reliability prediction of complex radar antenna array with an application example.By analyzing the composition and function characteristics of complex radar antenna array,considering the influence of component distribution on system reliability,a reliability block diagram of tree structure is established.The MTBCF prediction of antenna array is carried out by Monte-Carlo method,and the effect of the prediction used in this paper is compared with the traditional prediction,and a better accurate reliability prediction result is obtained.
