摘　　要：在某相控阵天线设计中,需要对铅垂放置的天线单元的方向图赋形。本文采用最小二乘法得到天线单元各振子电流的幅度和相位,并用MATLAB进行方向图计算仿真;根据计算结果,设计了幅相分配网络,并用HSFF仿真软件进行模型仿真;应用矢量网络分析仪对实物进行测量。测量结果表明,天线单元铅垂方向图与计算、仿真结果一致,满足设计要求。Shaping vertical pattern is an important content in designing phased array antenna. This paper describes a method which, through adopting Least Square method, obtains the amplitude and phase of current for the elements of antenna unit. The algorithm is simulated by using MATLAB. An amplitude-phase distribution network is designed, and the model is simulated by using HSFF. The test results show that the vertical pattern of antenna unit is consistent with the results of the calculation and the simulation, and meets the requirement of design.
