摘　　要：流星余迹通信不同于传统的通信,它是低速率通信,具有突发、不连续以及不定时的特性。流星余迹通信的复杂性要求有必要对其通信信道进行研究。可用流星率、占空比、平均持续期、等待时间和通信通过量是影响流星余迹通信信道性能的重要参数。根据偶发流星日心空间和地心空间的几何关系,得到了流星突发通信信道参数预测模型;并对流星通信链路观测的数据进行统计分析,得到流星余迹通信信道的各参数,预测结果和通信链路观测结果比较一致,为流星通信系统的建立提供了技术支持。Different from traditional communications, meteor trail communication is of low data rate communication with characteristics of b,rst,discontinuity and unfixed timing. It is necessary to research the meteor trail communication channel due to its complexi- ties. The available meteor rate （ MR ）, duty cycle （ DC ） , average burst duration （ ABD ） , waiting time （ WT ） and throughput （TP） are important factors impacting on channel of the MBC links. According to the statistic results of observed data of one communication link, the parameters of meteor trail communication channel are obtained. By constructing the geometric relationship of the heliocentric and the geocentric space of sporadic meteor, the theoretic predicton models of meteor burst communication（MBC） channel parameters are derived. These models are applied in MBC links . The results predicted by these models conform to the observations. The results given herein are helpful to research the properties of meteor trail communication channel and construct meteor communication system.
