摘要

本文给出了von Mises-Fisher散射通道中时空相关函数的简单解析表达式。与以往的结果相比，本文给出的表达式是精确的，并且仅基于初等函数，清楚地揭示了底层散射参数的影响。通过与数值积分的比较验证了推导结果，其中观察到精确匹配。为了证明它们的实用性，所提出的结果用于分析不同天线阵列几何形状之间的空间相关性，并研究来自运动目标的波动雷达信号的时间相关性。

Correlation Properties in Channels With von Mises-Fisher Distribution of Scatterers

This letter presents simple analytical expressions for the spatial and temporal correlation functions in channels with von Mises-Fisher scattering. In contrast to previous results, the expressions presented here are exact and based only on elementary functions, clearly revealing the impact of the underlying scattering parameters. The derived results are validated by a comparison against numerical integration, where an exact match is observed. To demonstrate their utility, the presented results are used to analyze spatial correlation across different antenna array geometries and to investigate the temporal correlation of a fluctuating radar signal from a moving target.
