Abstract行星聚合和太阳闪烁是影响深空通信的重要因素.分析,行星聚合和太阳闪烁的物理特性,建立了弱太阳闪烁条件下深空通信信道的Rician模型,并得出了当Rician因子大于10dB时近似为高斯信道的结论.对弱太阳闪烁下X波段和Ka波段的通信性能进行了仿真,这对建立可靠的深空通信链路具有十分重要的意义.
Other AbstractSolar scintillation effects can be significant for deep-space telecommunication links at small Sun-Earth-Probe (SEP) angles. Severe scintillation can make the telecommunication link unavailable.The physical characteristics of solar conjunction and scintillation are presented, the Rician channel model is set up, and the Gaussian approaches of communications channel are obtained once Rician factor exceeds 10 dB in deep space exploration due to weak solar scintillation. At last,we simulated the weak scintillation effects on telemetry signals at both X-band and Ka-bandthe model.
