1.本文介绍了宽带园柱形多波束透镜天线及有关数据。讨论了该天线360度覆盖和在不同方向上以较高灵敏度同时观测的可能性,以及以单脉冲测向方式能达到的测向距离、截获概率和精度。较详细地讨论了一些有关部件,例如馈电元件以及多倍频程频段内如何控制这些馈电元件对透镜的照射,如何避免这些馈电元件引起的孔径阻塞等。给出了测量数据。
1. This paper introduces broadband cylindrical multi-beam lens antenna and related data. The possibility of 360-degree coverage of the antenna and simultaneous observation with higher sensitivity in different directions is discussed, as well as the DF distance, interception probability and accuracy that can be achieved by single-pulse DF. Some related components such as feed elements and how to control the irradiation of these feed elements on the lens in the multi-octave band are discussed in more detail, and how to prevent the aperture clogging caused by these feed elements and the like are discussed in more detail. The measurement data is given.
