摘要

摘要：为了解决大型固定翼无人机应急基站覆盖范围小、覆盖不连续的问题，提出一种无人机应急基站连续覆盖的设计方案。通过对机载基站单天线覆盖能力的分析，提出内侧天线加边缘天线的多幅天线覆盖方案，并结合无人机飞行的滚转角、俯仰角等参数，设计保证连续覆盖的多天线挂装的安装方案。根据 3GPP 传播损耗模型进行链路预算，根据连续覆盖面积需求，规划无人机飞行方案。仿真和飞行测试结果表明，所提方案能在不使用云台智能控制天线角度的情况下，实现空中移动基站对地面50 km

面积的连续覆盖。

Abstract

To solve the problem of small coverage area and discontinuous coverage of large fixed-wing aerospace emergency base stations

a design scheme for continuous coverage of UAV emergency base stations was proposed.Based on the analysis of the coverage capability of the single antenna of the airborne base station

a multi-antenna coverage scheme with inner antenna plus edge antenna was proposed.Taking the roll

angle

pitch angle and other parameters of the UAV flight into consideration

the installation plan of multi-antenna mounting that guarantees continuous coverage was designed.Then the link budget was carried out according to the 3GPP propagation loss model

and the UAV flight plan was planned according to the continuous coverage area requirements.Simulation and flight test results show that the proposed scheme can achieve 50 km

continuous signal coverage of the ground by the mobile base station on the UAV without using the intelligent control of the antenna angle of the PTZ.
