在相控阵天线阵面设计中,为降低系统复杂性及工程成本,通常采用子阵技术来实现。同时,为了较好地抑制栅瓣,文中引入了多联骨牌子阵,给出了两种采用不同子阵结构和排列方式的天线阵列,并对有限视场下的扫描特性进行了仿真。通过对仿真结果进行对比和分析研究,验证了多联骨牌子阵实现阵列方向图低副瓣的有效性。最后,提出了采用多联骨牌子阵进行天线阵列设计需要进一步研究的方向。

In the design of phased antenna array system, subarray technology is usually adopted to reduce system complexity and engineering costs. Simultaneously, in order to suppress the grating lobes, the subarray of polyominoes is used. Two kinds of antenna arrays with different subarray structures and arrangements are presented. And the scanning characteristics in the limited field of view are simulated. By comparing and analyzing the simulation results, the validity of the low sidelobes for the array pattern of polyomino subarray is verified, which has referrence value for engineering application. In the last, the farther direction of designing antenna array using polyomino subarray is proposed.
