摘要

衰落是高频通信中的一个严重问题。它主要是由电离层折射率的随机不规则性引起的。解决这一问题的成功方法之一是空间多样性接收。本文利用几何光学和单散射近似推导了接收信号波动的空间相关函数。然后利用相关函数计算两接收天线之间所需的距离以获得不相关信号。研究结果为空间分集系统的优化设计提供了依据。

Spatial correlation function of the sky wave for use in space diversity reception

Fading is a serious problem in HF communication. It is caused primarily by the random irregularities in the refractive index of the ionosphere. One of the successful solutions to this problem is the space diversity reception. In this work the spatial correlation function of the received signal fluctuations is derived using geometric optics and single scattering approximations. Then the correlation function is used to calculate the required distance between the two receiving antennas to obtain uncorrelated signals. The results provide the base for the optimum design of the space diversity system.
