Abstract: To study the influence of atmospheric space environment on satellite communications, the weather conditions were divided into clear sky, cloudy and foggy weather, rainy and snowy weather. The satellite channel propagation characteristics were researched under different weather conditions. The Rice model, C.Loo model and Suzuki model were established respectively. The three-state Markov process was introduced into the satellite channel model, which could describe the transformation of the channel states caused by the weather change. The statistical characteristics of the satellite channel three-state Markov model were analyzed. Finally, the satellite channel three-state Markov model was designed and simulated based on the sum of sinusoid method and the measured data of meteorological satellite cloud image. The simulation results show that the proposed model can be used in the simulation of actual satellite channel propagation characteristics.

Key words: weather condition, multipath effect, shadow effect, channel model, Markov model

摘要: 为研究大气空间环境对卫星通信的影响,将卫星通信的天气状况分为晴朗天气、云雾天气、雨雪天气3种情况,分析不同天气状况下的卫星信道传播特性并建立相应的Rice分布模型、C.Loo分布模型和Suzuki分布模型,引入三状态Markov过程实现因天气变化造成的信道状态的转换,构成卫星信道三状态Markov模型并对该模型的统计特性进行分析。最后,采用正弦波叠加法并利用实测气象卫星云图数据对该卫星信道三状态Markov模型进行仿真实验。仿真结果表明,所建模型可以用来模拟实际的卫星信道传播特性。
