摘要
分析研究了流星前向散射通信链路和黄道坐标系统的关系,推导出偶发流星日心分布到地心分布密度的转换过程,得到了偶发流星的理论辐射分布(SporadicMeteor Radiant Distribution)模型。并运用该理论预测模型建立了一通信链路上空流星辐射分布,同时对可用流星率进行预测并和观测数据进行对比,结果比较一致,为流星通信系统的建立提供了技术支持。
By investigating the relationship of meteor signals over forward-scatter links and ecliptic coordinate system, the transformation process from the heliocentric to the geocentric radiant distribution of sporadic meteor is derived, and the theory model of the Sporadic Meteor Radiant Distribution (SMRD). The SMRD prediction model is applied in Yinchuan-Qingdao communication links. The meteor rate (MR) predicted by this model has good agreement with observation data. The model given herein can be helpful to construct meteor communication system.
