电磁波天线阵辐射角分布的计算机展示

利用计算机代数系统(CAS)Maple，实时计算与展示了电磁波天线阵辐射角分布的图样，天线阵的阵元数、元间距和阵元之间的位相等因素处理为程序交互式输入的参数，使各个因素之间复杂的相互作用对天线阵辐射角分布的影响得以即时快速形象地展示，该文分别分析了纵向排列和横向排列的天线阵的情况并展示了一些典型的分布花样。

Study of the angle-distribution of electromagnetic radiation for antenna array

Using the Computer Algebra System (CAS) Maple, a real-time computing for the angle-distributions of the array can be completed and the plots can be presented. The number of the array elements N,the space between each two adjacent elements d and their phase difference α are treated as the parameters of the program, which can be chosen freely so as to obtain some special patterns. Practically, both the longitudinal arrangement array and the transverse arrangement array are analysed and their typical patterns are presented.
