利用传输矩阵法，将天线罩等效为均匀多层介质平板，对其功率传输系数作了分析，并利用遗传算法对介质层厚度进行了优化，并以此法对某型天线罩所作的优化结构设计达到了预期效果。

The transmission method is employed to analyze the transmission properties,the radome is considered as equality multilayer medium flat. And the GA is used to optimize the thickness of medium. The utility of this technique has been illustrated by designing a radome.
