摘要
为缓解通信卫星频谱资源紧张程度,高通量卫星通信系统正向Q/V频段发展,毫米波在空间传播过程中容易受到沙尘粒子的散射和吸收作用而产生衰减,论述了电磁波在沙尘天气中传播的衰减模型,通过MATLAB编程利用电磁波在沙质媒介中传播的衰减模型进行仿真计算,得到不同仰角、不同频率下电磁波衰减量对能见度的依赖关系,量化了高频电磁波在沙尘天气中的传输损耗,为未来国内Q/V高频段卫星通信系统建设提供理论依据.
Abstract
In order to alleviate the spectrum resource shortage of communication satellites,the high-throughput satellite communi-cation system is developing forward to Q/V band.Millimeter wave was easy to be attenuated by the scattering and absorption of dust par-ticles in space.The attenuation model of electromagnetic wave propagation in dust weather was discussed.The attenuation model of electromagnetic propagation in sandy media was used for simulation through MATLAB programming,and the dependence of electro-magnetic wave attenuation on visibility under different elevation angles and different frequencies was obtained.The transmission loss of high frequency electromagnetic wave in dust weather was quantified,which provides for the construction of domestic Q/V high frequen-cy satellite communication system in the future theoretical basis.
