摘　　要：结合已有流星余迹理论和实测数据,提出一种判定是否存在流星余迹突发及其到达时间间隔服从哪种参数分布的方法,并用C++程序模拟,统计出时间间隔服从的参数分布形式,并利用该参数的分布规律进行流星余迹信道建模。信道建模时,判断流星余迹的发生类型,并对两种类型流星余迹发生的次数做了统计,得到了接收功率的衰落曲线,并与实测数据功率曲线进行分析比较,结果显示与实测数据基本符合。Combining the existent theories with the limited measurement data,a method for determining the existence of meteor burst and the corresponding distribution rule of arriving interval is proposed,and the whole process simulated with C＋＋.The channel model is built up with the data obtained from the first step,then the type of the meteor is determined,and the statistic on the times of meteor is done,finally the curve of the receiving power is obtained,and compared with the measured data.The final result is basically conformable with the actually-measured data.
