Comparison of Meteor Burst Channel properties in Antarctic and Middle latitude

当流星进入地球大气层时，它们会提供能够反射甚高频无线电信号的电离轨迹。流星爆发通信（MBC）是利用这条轨迹进行超视距无线电通信的一种。从2002年开始，连续3年在南极进行了一些有关MBC的试验。据推测，观测结果中含有极区特有的性质。但是，用于比较的中纬度地区观测资料不足。在此基础上，构建了基于技术学院（KOSEN）的MBC信道观测网，并对极区和中纬度的MBC信道特性进行了比较。

When meteors enter the earth's atmosphere, they provide ionized trails capable of reflecting VHF radio signal. Meteor Burst Communication (MBC) is one of beyond line of sight radio communication using this trail. Some experiment regarding MBC was performed in Antarctic for three years since 2002. It is guessed that the observation result contains peculiar properties of polar region. However, the observational data in mid latitude region for the comparison is insufficient. Then, the observation network of MBC channel is constructed based on Technical College (KOSEN), and the properties of MBC channel is compared between polar region and mid latitude.
