| 摘 要： | 以均匀分布的圆形天线阵列为模型,入射信号分别为均匀、高斯和拉普拉斯能量分布和三种双边带分布时,推导出其空间相关性的精确和近似表达式,分析了在入射信号为双边分布时各种因素对于其空间相关性的影响。仿真分析结果表明,双边带分布时相关性波动幅度和差值取决于中心到达角之间的差值。

| Abstract: | This paper derives spatial correlation functions of a uniform circular antenna arrays for three type of angle-arrival（AOA） distributions and their bi-modal distributions.Three different AOA distributions are considered in this paper：a uniform angular distribution,a Gaussian angle distribution,and a Laplacian angle distribution.The generalized spatial correlation functions are investigationed carefully by exact and approximate analyses.The results show that the oscillation of correlation function depends on the difference between the AOA＇s of the two modes. |
