| 摘 要： | 针对目前流星雷达测距误差大的问题，本文提出了提高流星雷达测距精度的新方法，即提高采样速率，用相关分析确定回波脉冲参考点的方法。该方法使流星雷达的测距精度提高一个数量级，测距误差降到±１４ｍ，使流星雷达不仅可以用来观测研究流星，还可用于监测飞机、火箭的飞行等，扩大流星雷达的应用。

| Abstract: | There is a big error in distance measurement via meteor radar at present. Here we propose a new method,which adopts very high sampling rate and identifies the reference point of echo pulse signal by correlation analysis. It would greatly reduce the error of distance measurement and make meteor radar not only be used for measuring meteor tail but also be used for other purpose such as monitoring airplane and rocket and so on. |
