摘要

本文采用遗传算法分两步优化矩形波导裂缝天线阵

首先对天线阵元激励幅值进行了初步优化

直接利用可分离型分布

大大简化了初步设计的过程

并将阵元激励幅值比值作为优化参量以利于波导结构的馈电;在随后进行的波导裂缝阵列阵元的偏置量和缝隙长度的优化上动态处理阵元的互耦并结合Elliott设计思想

采用遗传算法得出的3cm(1×4)缝阵结果验证了GA算法的有效性和准确性

并完成了72元矩形波导裂缝阵列的阵面优化

为大中型阵列优化提供了一种有效的方法.

Abstract

Genetic algorithms(GAs)

one of the global maximum method

was firstly used to the elementary optimization of the amplitude of the slots in the rectangular slotted waveguide array

which simplify the design procedure greatly.Secondly

GAs

combined with the dynamic mutual coupling among all the slots were applied to optimize the offsets and the resonant lengths of the slots

which were the key factors of the antenna arrays.The results of the small array show the the validity of this method

the array of medium size (72 elements) array is also analyzed

and the same method can be extended to the large array design.
