摘要
讨论比较了四种现代优化方法的基本原理和内容。据此选择遗传算法建立了一种耦合渐变槽线天线的多目标优化模型 ,用于设计单脉冲系统的和差波束印刷天线。详细讨论了应用遗传算法的具体步骤 ,经计算得出的天线性能达到了预期的优化目标 ,并得到实测数据的验证。
In this paper, the principles of several modern optimization methods with their analysis processes are compared. A multi-objective optimization model of a coupled tapered slot-line antenna (CTSA), which radiates sum/difference beams for a mono-pulse system, is established by means of the Genetic Algorithm. The procedure of the algorithm is described step by step. The computation results approach the desired performances of both the sum and the difference-beams of the antenna, which are verified by the experimental data too.
