气象数据融合的星地激光链路多物理场损耗分析
Analysis of multi-physical field loss in satellite-to-ground laser links with integrated meteorological data
摘要
Abstract
To investigate the impact of actual meteorological parameters on the communication performance of satellite-to-ground laser communication systems,a model for atmospheric channel received power loss based on wind speed and visibility parameters was constructed.The Hufnagel-Valley turbulence model and the Von Karman power spectrum were employed,com-bined with the fast Fourier transform method to generate atmospheric turbulence phase screens.Mie scattering theory was intro-duced to quantify the fog attenuation effect.Simulation results indicated that turbulence intensity is positively correlated with spot dispersion,laser energy attenuation,and received power loss.In light fog conditions,the received power remained rela-tively stable,whereas under turbulence influence,the fluctuation of received power significantly increased.In a combined envi-ronment of heavy fog and turbulence,the system's received power could drop to-85.64 dBm,and the probability of communi-cation interruption reached 38.33%when wind speeds were at or exceeded 15 m/s.关键词
