中文摘要：
本文提出一种新型综合阵列天线方向图的模式方法.该方法基于双正交模式理论,考虑了阵元之间的耦合作用的影响,可以对任意形状的阵列天线进行方向图综合.利用双正交模式综合方法可以快速有效地获得每个阵元的特定激励,以期阵列天线的方向图满足特定的需求.模式组之间的双正交特性保证了该方法所得天线阵列方向图与期望方向图之间良好的一致性.通过对所需电场的加权,可以将整个球面上的二维曲面积分运算转化为一维线积分运算,使得方向图综合过程的计算量大为减少.若干阵列天线方向图综合实例验证了该方法的正确性和有效性.
英文摘要：
A novel approach to arbitrary array pattern synthesis based on biorthogonal modes is presented in this paper. The algorithm involving arrays with arbitrary geometry and incorporating mutual coupling effect, can accurately determine element excitations required to yield desired patterns. The mutual orthogonality of modes is used to ensure the agreement between the desired and computed patterns. When the weighted field is applied, the double integral can be simplified by performing one variable integral, so synthesis procedure is less time-consuming. The effectiveness of the approach is demonstrated with several numerical examples.
