摘要
利用椭圆口径与圆口径阵列天线方向图函数之间的等效关系,将圆口径Taylor综合方法应用于单元数为2132,未知量为486546的椭圆口径微带天线阵列,并采用并行高阶矩量法计算其辐射特性,得到理想的低主副瓣电平比。高阶矩量法具有计算精度高、未知量少、节约计算资源等优势。大规模并行计算可以极大地提高计算效率。本文结果表明该方法可以有效地解决工程上大规模的复杂问题。
With the equivalent relationship between circular and elliptic apertures, the Taylor synthesis is applied to an elliptic aperture with 2132 elements and 486,546 unknowns. Meanwhile, the parallel higher-order method of moments(Mo M) is used to analyze the radiation patterns of the arrays, and numerical results show that the side-lobe levels achieve the design parameters. The higher-order MOM has the advantages of high accuracy, less unknowns and saving storage requirement. The massively parallel computing can largely improve computational efficiency and decrease simulation time. The results show that this method can be used to solve large-scale complex problems in engineering.
