beamwidth of array antenna 阵列天先波束宽度
With the aid of a computer, curves of beamwidth and side lobe versus the antenna parameters are plotted.
并借助计算机绘出了主瓣宽度和副瓣电平与天线主要参数的关系曲线；
The one-dimensional phased array antenna discussed in this paper needs to radiate a narrow beamwidth and low sidelobe pattern on the horizontal, a sum and difference beam on the vertical.
所设计的一维扫描相控阵天线在方位面具有窄波束、低副瓣特性，在俯仰面实现和差波束。
