摘要

分析了互耦机理及其对接收信号矢量的影响，详细推导了入射信号角度谱服从Von Mises分布时，任意数目线型、圆型及面型等不同流型阵列的天线空间相关系数的闭式表达式和近似表达式，并据此推导出了综合互耦因素的对应流型阵列天线的相关系数解析式。仿真结果表明：本文推导的天线空间相关系数表达式与数值积分结果非常吻合。另外，在互耦效应下，天线阵元相关性围绕着无互耦时的相关性曲线上下波动，且面型阵列具有更好的抗互耦能力。

Abstract

The mechanism of MC and its impact on the received signal vector were analyzed.A closed-form expression and an approximate expression of SC for antenna arrays with different forms were derived

where the power angle spectrum of arrival signal was modeled as Von Mises (VM) distribution.On this basis

the general expressions of SC with MC effect was derived.Simulation results show that the proposed analytical expressions are in good agreement with the numerical integration results.In addition

under the mutual coupling effect

the correlation of antenna array elements fluctuates around the correlation curve without mutual coupling

and the planar array has better resistance to mutual coupling.
