本文叙述一种由偏置线源照射的抛物柱面反射器组成的天线。为了获得360°方位复盖,这种天线围绕柱面轴作机械转动。仰角复盖与测高是通过在线源内采用移相器的电扫方法实现的。文中提出了一种新的镜象概念,它使分析简化,并有助于更好地理解这一设计的原理。本文还介绍了低旁瓣特性及使反射器尺寸减至最小的综合方法。 This article describes an antenna consisting of a parabolic reflector that is illuminated by a bias line source. In order to obtain 360 ° azimuth coverage, this antenna rotates around the cylindrical axis. Elevation angle coverage and height measurement are achieved by the electro-swept method using a phase shifter within an in-line source. The article presents a new concept of mirroring that simplifies analysis and helps to better understand the principles of this design. This article also describes low-sidelobe characteristics and an integrated approach to minimize the size of the reflector.
