摘要
论文讨论实际误差对加权最佳稀布阵列的几个主要性能指标(主瓣增益、波束宽度、指向、副瓣电平)的影响,并给出了几种主要误差的容限。还专门讨论了阵元失效和互耦对天线性能的影响。主要结论都有计算机结果佐证。
The paper deals with the influences of practical errors on the properties, including mainbeam gain, bcamwidth, pointing error, sidelobe level, etc., of the optimum thinning linear arrays. Then the tolerances on several main error sources are given. Particularly, the effects of clement failure and mutual coupling on the performance of an antenna arc dis- cussed. The main results presented in this paper are demonstrated by the computer simulations.
