1991年夏,我们利用自制的单站闪电探测及定位系统(M-LDARS),在北京地区进行了对比实验,并对所记录的地闪回击信号作了分析。本文提出了我们得到的北京地区云地闪回击信号的峰值时间、半峰时间、峰值电流以及电流上升率的统计分布和频谱特征的典型结果,并与国内外同类观测的结果进行了对比。

In the summer of 1991,we performed a lightning location experiment in Beijing by using the Monostatic Lightning Detecting and Ranging System(M-LDARS),with dipole antenna,which manufactured by ourselves.By analysing the record of return strokes,we have obtained the typical characteristics of the strokes,some parameters about the electric field radiation and its spectra.This result is reasonably comparable with other published work.
