摘　　要：关于动中通系统中普遍采用抛物面天线,可使得系统小型化难度增加,为优化最佳天线方案,采用平板天线取代抛物面天线可以部分改善。为促进动中通技术在车载平台中的应用,提出了超低轮廓相控阵天线方案,使得平板相控阵天线的高度进一步降低。针对孔径效应和孔径渡越时间限制问题,给出了时延相位两级补偿的方法,有效扩展了天线系统的工作带宽;同时采用遗传算法调整天线阵因子相位,对多板相控阵天线方向图的副瓣高度实现了优化。仿真结果表明,多板天线方案可以实现性能对平板天线的逼近,并很好的适应了车载平台对天线高度的严格要求,有较高的工程实用价值。To reduce the height of the planar phased array antenna is a key problem in satellite communication on the move （SOTM）. A scheme of multi - panel phased array antenna can resolve it. The method of two - class phase compensation is given in order to resolve the problems of aperture effect and aperture transition time of the phased antenna . This technique improves the bandwidth of the antenna system. The SLL of a multi - panel phased arrays is op- timized by adjusting phases of sub - arrays on genetic algorithm（GA） in this paper. As a final example, the design specification for the multi - panel phased arrays is given. Successful applications show that the GA can be used as a general tool for pattern synthesis of the multi - panel phased array antenna.
