波束切换机载测控天线的设计方法

一种波束切换机载测控天线的设计方法

内容简介：机载测控天线采用定向波束切换天线，不仅可以提高天线的增益，而且可以提高系统的抗干扰能力。采用全向天线单元组阵、通过简易波束控制实现的波束切换天线，具有电气性能好、控制方法简单和可实现性好等特点。介绍了7单元圆形阵列结构波束切换天线的工作原理以及采用简易相位控制实现波束切换的方法，并给出了天线的实测结果，验证了设计方法的正确性。

Abstract：For airborne TT&C antenna,the directional beam-switched antenna can be used to improve antenna gain and system anti-jamming capability.The beam-switched antenna,which is realized by omnidirectional antenna unit array and simple beam control, has such characteristics as good electrical performance,simple control method and good feasibility.The paper introduces the operating principle of the beam-switched antenna with 7-unit circular array and the method of beam switching by simple feed phase control,and gives the measurement results,which validates the design method.
