摘要：

有源相控阵天线系统的部件失效会造成天线增益、副瓣电平等性能参数的恶化。在考虑了天线单元幅度和相位的随机误差呈正态分布后,以部件失效的概率分布为依据,分析了包括天线单元失效、子阵失效以及组件失效情况下,天线性能随之变化的趋势。通过算例仿真得出,在文中建立的不同部件失效的数学模型下,天线增益的变化相对平缓,而副瓣抬升则相对较大。计算结果及结论可用于实际相控阵天线性能的评估和工程设计。

关键词: 部件失效, 有源相控阵, 天线增益, 副瓣电平

Abstract:

The sub-system failure can cause poor performance of active phased array,including the loss of gain and depravation of side-lobe level.With the normal distribution of random error on antenna elements of amplitude and phase in consideration,the variety of array performance is analyzed versus the antenna element failure,sub-array failure and TR module failure.Simulation results show that the deterioration of gain is less than that of side-lobe level,which are referential to the performance evaluation and project design of phased array antenna.

Key words: sub-system failure;active phased array;antenna gain;side-lobe level
