流星的特性与流星雷达的初步设计The Character of Meteors and the Preliminary Design of Meteor Radar

摘要(Abstract):
每天有许多大小不同的流星进入地球大气层,其中绝大多数被燃烧尽,并在它的路径上留下了光亮的离化的尾巴。大的流星尾巴可被肉眼看见,但最经常出现的是那些亮度相当于15等星以上的小尾:这些小尾成了雷达探测的目标。在第二次世界大战期间,雷达出现后,流星的研究才开始使用雷达技术。到目前为止,世界上发达国家已经建立了许多专门用于探测研究流星的雷达,而且也取得了一批重要的研究成果。本文简要的叙述流星及流星尾的物理特性,流星雷达的工作原理及如何设计选择流星雷达的有关参数,并给出了在陕西天文台建立流星雷达的基本参数。
