干涉仪测向天线孔径对GSM频段测向精度影响初探

内容简介：针对相关干涉仪测向查表算法，以三种不同孔径的5单元均匀圆阵为例，通过理论和仿真分析在GSM频段内，信号频率变化和来波方向的变化对测向精度的影响情况。得出天线阵孔径越大，测向精度越高，但测向模糊也随之增加的结论。为GSM频段测向系统的工程应用提供理论依据。

Abstract：According to table searching algorithm of correlative interferometer ,three dimensions of five antenna array were given.Analying the effect of frequency and direction on direction finding accuracy in GSM band ,by theory and simulation mod-el.The paper concluded that the largest antenna array has the highest direction finding accuracy,and also the worst direction fin-ding ambiguity.
