在大型阵列天线的设计中,应用不规则的多联骨牌子阵可以有效地抑制栅瓣,降低工程成本。在多联骨牌子阵划分阵列的基础上,文中通过遗传算法进行幅度和相位优化,对仿真结果进行对比和分析研究,实现了多联骨牌子阵天线阵列方向图的低副瓣性能和较高的口径效率。

Irregular polyomino subarrays can be applied into the design of large array antenna, because of their advantages such as effectively suppressing the grating lobe and reducing the cost of engineering. On the basis of polyomino subarray, amplitude and phase optimization is carried out by adopting the genetic algorithm in this paper. To compare and analyze the simulation results,the low sidelobe performance and the high aperture efficiency of the array are obtained.
