摘要

雷电定位系统是雷电物理和雷电防护领域的一个热点问题。当雷电放电产生的甚低频电磁辐射信号传输距离较远时

基于互相关函数的时差法往往不能准确进行雷电定位。基于此

文中深入研究了群到达时间法定位基本原理

并探讨了GPS时间误差、相位测量误差和频率测量误差对定位精度的影响。结果表明

采用群到达时间法进行雷电定位是可行的;GPS时间误差和相位测量误差导致定位误差较小

而频率测量误差对定位精度影响较大。

Abstract

Lightning location systems have received much attention in the fields of lightning physics and lightning protection.When the transmission distance of VLF electromagnetic radiation signal generated by lightning discharge is long

the time difference method based on cross-correlation function is often unable to accurately locate.In this paper the principle of time of group arrival method are investigated

and the effects of error of absolute time determined from GPS

phase measurement

and frequency measurement on lightning location accuracy are analyzed.It is shown that it is feasible to use time of group arrival method for lightning location.The effects of error of absolute time determined from GPS and phase measurement on lightning location accuracy are small

however

the effect of error of frequency measurement on lightning loc ation accuracy is comparatively larger.
