任意天线的最低旁瓣方向图综合问题是“阵列天线分析与综合”课程教学中的难点和重点。本文针对最低旁瓣方向图综合问题的特殊性,利用凸优化的优良数值求解特性,结合CVX凸优化工具箱,对任意阵列天线的最低旁瓣方向图综合算法进行了详细的讲解。教学实践表明,将CVX工具箱引入到“阵列天线分析与综合”课程中,研究任意天线的最低旁瓣方向图综合问题,具有简便易学、编程简单、直观易懂等优点,不仅可以让抽象的理论形象化、具体化,而且有效提升了学生分析问题和创新意识的培养。
The synthesis of the lowest sidelobe pattern for any antenna is a difficult and important point in the teaching of Array Antenna Analysis and Synthesis. In this paper, according to the particularity of the synthesis of the lowest sidelobe pattern, the synthesis algorithm of the lowest sidelobe pattern of any array antenna is explained in detail by using the excellent numerical solution of convex optimization and CVX convex optimization toolbox. The teaching practice shows that introducing the CVX toolbox into the course of “Array Antenna Analysis and Synthesis” and studying the synthesis of the lowest sidelobe pattern of any antenna has the advantages of easy and easy to learn, simple programming, intuitive and easy to understand, Abstraction of the theory of visualization, specific, but also effectively enhance students’ analytical problems and the cultivation of innovative awareness.
