北斗调零天线阵列设计研究
首发时间:2009-05-13
摘要: 介绍了一种我国北斗卫星定位系统抗干扰接收机射频前端的调零天线阵列。基于功率倒置(PI)算法和天线原理,设计出的天线阵列实现了自适应调零天线各项指标。重点介绍了调零原理、天线阵列设计和对天线单位阵元的设计与仿真,同时介绍了微带天线的基本理论和圆极化天线的科学测试方法,便于准确实现天线的指标和各单元的一致性情况。该北斗调零阵列天线对卫星导航信息信号稳定性有特殊要求和电磁环境恶劣的场合有重要作用。

Design and Research of BeiDou Nulling Antenna Array
Abstract:This paper completes the design of anti-jamming nulling antenna array of BeiDou satellite navigation system. This array antenna which based on power-inversion(PI) arithmetic and adapting antenna theory, can achieve all kinds of target of adapting nulling antenna. This paper provide the design of nulling theory and array antenna, including simulating, and introduce basic theory of microstrip antenna and exact testing method of circular polarization antenna. This BeiDou nulling antenna array can be widely used in many locations such as the case in wicked electromagnetic environment or some system which have special demand to satellite navigation information.
Keywords: nulling antenna satellite navigation microstrip antenna antenna array
