| 摘 要： | 为提高无人机(unmanned aerial vehicle,UAV)毫米波通信场景传播特性的分析精度,基于抛物方程(parabolic equation,PE)理论建立了一种无人机通信场景传播特性分析方法,并针对都市和郊区两种典型无人机空地通信场景下的传播特性进行仿真。结果表明,提出的方法能够有效地反映地形地物变化对无人机空地通信信号传播产生的影响,对比ITU-R统计预测方法,两种场景下预测结果趋势均保持一致。该方法可实现毫米波无人机应用场景传播特性有效预测,对无人机毫米波通信系统设计、研制、测试等环节提供支撑。

| Abstract: | To improve the analysis accuracy of the propagation characteristics of UAV millimeter-wave communication scenarios, a method based on the parabolic equation was developed to analyze the propagation characteristics of UAV communication scenarios and simulate the propagation characteristics in urban and suburban areas.The results show that the proposed method can effectively express the influence of terrain parameters on the UAV air-ground communication link.Overall, the prediction results are consistent with the ITU-R statistical method in both scenarios.Effective prediction of the propagation characteristics of millimeter-wave UAV application scenarios can be realized with the proposed method, which may support the design, development, and testing of UAV millimeter-wave communication systems. |
