| 摘要: |
| 围绕天线阵增益、波束宽度、指向和副瓣电平等指标，分析了幅相误差、阵元失效对稀疏阵列天线性能的影响。应用概率统计原理，导出了具有幅相误差、阵元失效时稀疏阵天线阵增益损失、波束宽度、指向、副瓣电平的估计公式、并得出一些有益结论。 |

| Abstract: |
| This paper analyzes the effects of amplitued-phyase errors and element failure on antenna gain，beam width，beam direction，and sidelobe level in sparse array. With the help of statistic principle，the estimtion ormulas of the antenna gain loss，beam width and siedlobe level in sparse array are derived. |
| Keywords: sparse array,amplitued-phase errors,element failure,gain loss,sidelobe level,beam width |
