beam antenna
[计] 定向天线组
- Another advantage is, most obviously, that the multi-beam antenna looks at seven different points simultaneously.
另一个很明显的优势，多波束天线在同一时刻观察着七个不同的方向。 - In satellite communications, pertaining to antenna systems with a beam for maximum cover of the earth's surface.
在卫星通信技术中，指天线系统其波束能最大程度地覆盖地球表面的区域。 - A sphere, in contrast, concentrates its beam to a line– which is why a" line feed" antenna was originally used at Arecibo.
球形的则不同，它会把波束汇聚到一条线上——这就是为什么阿雷西博先前使用的是“线反馈”天线。
