摘要
本文结合工程实际,采用并行高阶矩量法分析一个93单元数波导缝隙天线阵列的辐射特性。受限于计算资源,采用传统矩量法计算Ka波段波导缝隙天线阵列十分困难。高阶矩量法恰能大幅提高求解此类电大尺寸问题的能力,此外基于分块矩阵的高效并行策略能极大地提高计算规模并减少计算时间。文章最后通过与商业软件和实测结果对比,证明该算法有效性。
With the actual project, the high-order method of moments is utilized to simulate electromagnetic radiation of a slotted waveguide antenna array with 93 slots. The limit of computer storage resources makes it difficult to simulate Ka-band slotted waveguide antenna by the conventional MoM. The introduction of higher order basis functions can improve the ability of the MoM to analyze the electrically large targets. Furthermore,the parallel strategies based on block partitioning of the dense matrix can greatly improve the computational scale and reduce computational time. Finally, the agreement of the numerical res ult, the commercial software result and the measurement result is performed to demonstrate the validity of the scheme.
