摘　　要：提出用凸优化方法处理阵元失效问题,利用凸优化方法优化出未失效阵元的馈电幅度和相位,使得天线辐射波束的副瓣最低,从而对阵列失效位置和失效个数造成的波束性能影响进行评估。数值实验表明该方法计算速度快,求解方便,而且可得到全局最优解,对工程设计具有较大的指导意义。The problem of array element failure is solved by convex optimization method. The amplitude and phase of the array zero-failure elements is designed and optimized by convex opti- mization method to make the side lobe level of antenna beam lowest, which could evaluate the performance degradation in beam pattern because of the position and number of array failure ele- ment. The numerical experiments show the method is fast, convenient and could obtain the glob- al optimal solution, which is of great significance in the engineering design.
