摘要

针对现有无人机（UAV）空地信道几何统计模型（GBSM）对信号到达角和出射角分布的假设过于理想，无法准确描述UAV空地传播环境的空间统计特性，影响建模准确性的问题，面向基于圆柱散射体的UAV三维空地信道模型，从俯仰面和水平面详细分析了到达角和出射角对应散射区域的空间几何特征，进而推导得到角度分布的概率密度函数。通过仿真研究了信道模型的多种参数对概率密度函数的影响，证明了所提成果能够准确地刻画UAV空地信道到达角和出射角的分布，可为空地通信信道的准确建模提供支撑。

Abstract

To cope with the problem that the distribution assumptions of arrival angle and departure angle in existing geometry-based stochastic modeling (GBSM) for the unmanned aerial vehicle (UAV) air-to-ground (A2G) channel are too ideal to describe the spatial statistical property of the UAV A2G propagation environment precisely

considering the three-dimensional (3D) cylindrical A2G channel model

the spatial geometric characteristics of scattering regions were investigated analytically as corresponding to the angles of arrival and departure in both elevation and azimuth planes

which derived the probability density function (PDF) for the distribution of each angle.The effects of various parameters of channel model on the PDF were studied and simulation results prove that the derived PDF can describe the spatial statistical properties of UAV A2G channels more accurately

and can support the modeling of A2G communication channels well.
