Abstract

Abstract: In order to study the influence of multipath, shadows and the weather variations on meteorological satellite channel, the Suzuki and extension Suzuki channel models were studied according to the analyses on the different weather conditions. Then the two-state Markov model was introduced into satellite channel model, which could describe the transformation between two kinds of channel state models caused by the changes of weather. Finally, the meteorological satellite channel simulator was designed and simulated based on the the shaping filter method. The results show that the proposed meteorological satellite channel simulator can be used in the description of actual meteorological satellite channel propagation characteristics.

Key words: meteorological satellite, multipath effect, shadowing effect, channel simulator, Markov model

摘要： 为研究多径、阴影及天气变化对气象卫星信道的影响,分析信道传播特性并根据不同天气状况研究了贴近实际的卫星信道Suzuki模型和扩展Suzuki模型。引入两状态Markov过程,以反映天气变化或云的移动导致信道状态模型之间的转换。采用成形滤波器法设计了气象卫星信道模拟器并进行了仿真。仿真结果表明,所设计的气象卫星信道模拟器可以用来描述贴近实际的气象卫星信道传播特性。
