摘要 设计了宽频带波束扫描不等间距直线阵列天线。在阵列天线孔径尺寸、带宽和最大波束扫描角度给定的情况下,采用DE算法极小化直线阵在工作频带内扫描方向图的峰值副瓣电平,求得最优的阵元间距分布。仿真结果表明,不等间距排布方式可在工作频带内有效地抑制直线阵方向图的栅瓣。采用Ansoft HFSS软件对优化后的直线阵进行了建模仿真,HFSS仿真结果与优化计算结果基本吻合。 设计了宽频带波束扫描不等间距直线阵列天线。在阵列天线孔径尺寸、带宽和最大波束扫描角度给定的情况下,采用DE算法极小化直线阵在工作频带内扫描方向图的峰值副瓣电平,求得最优的阵元间距分布。仿真结果表明,不等间距排布方式可在工作频带内有效地抑制直线阵方向图的栅瓣。采用Ansoft HFSS软件对优化后的直线阵进行了建模仿真,HFSS仿真结果与优化计算结果基本吻合。
