固态有源相控阵天线中的单元失效与容差分析

Analysis of Element Failure and Tolerance in Solid-State Active Phased Array

本文主要讨论天线单元失效和容差对固态有源相控阵天线副瓣电平和增益的影响。应用概率统计原理导出了天线副瓣最高电平和天线增益损失的估计公式。计算结果和模拟结果表明,两者吻合较好。

The effects of element failure and tolerance on antenna sidelobe level and gain in solid-state active phased array is mainly discussed in this paper. With the help of statistic principle, the estimation formulas of the peak sidelobe level and gain loss are derived. The computation and simulation restarts show that good agreement is achieved.
