| 摘 要： | 为了分析水平和竖直放置的两种均匀圆阵的角度模糊特性,基于均匀圆阵数据模型和方向图特性,分别推导了2种圆阵的模糊角公式.根据导出的模糊角公式,系统分析了圆阵半径、阵元数和入射信号俯仰角对2种圆阵模糊性的影响.最后,进行了大量的计算机仿真实验.通过对比分析得出:在相同条件下,竖直放置的均匀圆阵的性能要比水平放置的均匀圆阵的性能好.

| Abstract: | In order to analyze the angle ambiguity characteristics of two types of uniform circular arrays placed horizontally and vertically,this paper derives the ambiguity angle formulae for such two types of two uniform circular arrays respectively,on the basis of their characteristics of data model and the radiation pattern.By using the ambiguity angle formulae derived,the influences of the circular array radius,numbers of array elements and angle of pitch of incidental signals on the two circular arrays ambiguit... |
