摘　　要：本文从实现相控阵面天线低副瓣性能的角度出发,针对在实际的相控阵天线设计中由于阵列天线单元间的互耦效应,用理想的电流分布作为激励往往达不到所期望的副瓣电平要求这一缺陷,首先用矩量法精确分析了考虑互耦影响时相控阵面天线阵元的电流分布,作出归一化电流幅度分布图,仿真实现了阵元互耦对相控阵面天线波束形成的影响效果,接下来用软件的方式补偿互耦所造成的影响,给出补偿的具体步骤,从而完成了相控阵天线波束形成的综合。In actual phased array antennas, we can not get the anticipant side lobes with the perfect current because of the mutual coupling domino offect. To realize low side lobes of phased array antenna ,method of moments is used to accurately analyze the distributing of current in phased array antennas with the effect of mutual coupling, unitary current extent distributing chart is protracted, and effects of mutual coupling on phased array antenna beamforming is simulated. Then, this article compensates the effect by software and gives material steps. Fially, the synthesis of phased array antenna beamforming is completed.
