摘　　要：地震、台风等突发事件期间,在常规通信手段故障或硬件设施遭受损毁情况下,亟需具备自主可控的应急通信能力。在电离层中释放特定的金属物质,可以在电离层中生成人工空间等离子体云,以此作为无线电波的强反射/散射区,有望实现自主可靠的远程超视距无线通信,可作为热点地区、深山、极端条件下的应急通信手段。本文基于人工等离子体云技术,开展了等离子体云的超视距传播特性数值模拟研究,建立了等离子体云各向同性散射模型,仿真了不同释放条件下,等离子体云散射场的功率密度分布特性,获得了人工等离子体云传播规律,为人工等离子体云超视距通信研究奠定了初步理论基础。During emergencies such as earthquakes,typhoons and so on,autonomous and controllable emergency communication capabilities are urgently needed when conventional communications means fail or suffer damage.Releasing specific metallic substances in the ionosphere can generate artificial plasma clouds in the ionosphere,forming artificial meteors.As a reflector,it is expected to realize autonomous and controllable remote wireless communication,and can be used as an emergency communication means in hot spots,deep mountains and extreme conditions.Base on artificial meteor technology,artificial meteor over-the-horizon channel characteristic and artificial meteor isotropic scattering model are studied.The power density distribution characteristics of artificial meteor scattering field under different conditions are simulated,which provides theoretical basis and technical support for the experiment of artificial meteor over-the-horizon communication and the research of over-the-horizon channel.
