Abstract: 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.
