流星余迹通信是近三十年来发展起来的一种超短波远距离通信方式,它具有一系列独特的优点,很有发展前途,目前已进入实际应用。本文简单介绍有关流星余迹通信的几个问题,供读者参考。一、什么是流星余迹通信晴朗无月的夜晚(尤其在夏季),人们凝视天空,可以看到飞驰而过、瞬间即逝的流星。平均每小时用肉眼可以观察到2～20个流星。实际上,这仅仅是少数体积较大的流星,只是流星总数中的一小部分。据统计每天进入大气层且能产生有效电离余迹的流星多达几十亿 Meteor trace communication is an ultrashort-wave long-distance communication mode developed in the past 30 years. It has a series of unique advantages, promising future and has been put into practical application. This article briefly introduces some issues about meteor trace communication, for readers reference. First, what is the meteor trail communication Clear no moon night (especially in summer), people stare at the sky, you can see the speeding, fleeting meteor. The average hourly with the naked eye can be observed 2 to 20 meteors. In fact, this is only a small number of meteor meteor, but a small part of the total meteor. It is estimated that as many as billions of meteors enter the atmosphere daily and produce effective ionospheric tracks
