摘要
流星辐射分布在不同纬度的分布都各不相同,因此准确预测流星通信链路在不同纬度的流星辐射分布,从而改变大圆路径上天线的指向,以提高通信速率显得非常重要。根据流星轨道分布的特点,建立了流星轨道分布到流星通信链路的转换关系,推导出流星辐射分布纬度变化预测模型,并提出了求解模型的方法。将预测模型应用于流星通信链路,预测的结果和国外比较成功的预测模型预测的结果比较一致,为建立流星通信系统提供了技术支持。
The sporadic meteor radiant distribution （SMRD） varies with latitude; therefore it is very crucial to accurately predict the SMRD and thus to change the direction of antennae and improve the data rate. According to meteor orbit distributions,the transformation from meteor orbit distribution to meteor communication links is constructed,the latitude variability prediction model and simulation of meteor radiant distribution is derived,and a new method is proposed to compute the theoretical model,which is applied in meteor communication links.The results predicted by the model have good agreement with the successful prediction model abroad. The model given herein could be helpful to construct meteor communication system.
