摘要
本文首先分析了考虑和不考虑幅相误差时单元失效对天线增益和副瓣电平的影响,紧接着讨论了单元可靠性与系统可靠性的关系,并对天线副瓣电平随工作时间变化的趋势作了预测,最后给出了一些结论。
At first this paper analyses the effects of element failures on the antenna gain and the sidelobe level(SLL) with and without considering the array amplitude and phase errors. Then, the relationship between element reliability and system reliability is discussed,the trend of the SLL change with the operating time is predicted as well. Several conclusions are summarized in the end.
