Study on the influence of sandstorm on Q/V high throughput satellite communication system
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.
