基于太赫兹通信的高空飞机编队组网研究

Aircraft Formation Networking in High Altitude Based on Terahertz Communications

针对应用于航空通信场景的太赫兹通信,基于太赫兹波的高空传播特性,提出了同时包含确定信道和随机信道的高空太赫兹信道传输模型。对于确定数量的有人/无人飞机混合编队,以通信中断概率作为机间通信的可靠性指标,分析了给定中断概率阈值下高空太赫兹通信的最远机间距离。面向执行环境监测任务的飞机编队,提出了满足高空太赫兹通信可靠性指标的最大化编队监测面积的编队位置部署方案。仿真验证了理论推导的正确性,求解了最优编队部署,相比于考虑不完善的太赫兹高空信道模型,编队最优部署下的最大监测面积提升了约8%,为高速的高空组网提供有效支撑方案。

Utilizing the Terahertz wave propagation characteristics,this works studies both the deterministic channel model and the statistical channel model of high-altitude Terahertz channel transmission models for aerial communications.The study considers a given number of hybrid manned and unmanned aircraft formation.The inter-aircraft communication reliability performance of the derived propagation channel model is investigated in terms of the communication outage probability,and the maximum distance of Terahertz communication between aircraft is analyzed under the given outage probability threshold.To carry out the environmental monitoring,a formation deployment scheme that maximizes the formation monitoring area under the reliability index of the high-altitude Terahertz communication system is studied.Simulation results validate the correctness of the theoretical derivation and solve the optimal formation deployment.In particular,the maximum monitoring area is improved by about 8%compared with the defectively considered high-altitude Terahertz channel model,which provides an efficient basis for future high-speed high-altitude networking.
