| 摘 要： | 通过分析多站雷电定位系统MDF的特点,提出影响多站雷电定位系统探测效率的因素主要有两个方面:1)波形判据及阈值的设置;2)DF场地环境及其本身的时间分辨率。本文提出了一种估算系统因第二种因素存在时的探测效率的方法。用此方法分别计算和分析了北京DF网络三年来的探测效率。结果表明:1)该系统中各DF站在正常情况下(不考虑第一种因素)探测效率约为70％左右;2)若有大量干扰DF的探测效率会大大降低。

| Abstract: | By analyzing the characteristics of Magnetic Direction Finder (MDF) System, we suggest that there are two main factors which can affect seriously the detecting efficiency of Lightning Location Systems (LLS). One is the setting of wave shape criteria and amplitude threshold value.The another one is the environment of DF site and the limited processing speed of DFs and Position Analyzer (PA). Using a new estimation method of DF detecting efficiency developed in this paper, we have got some results on DF detecting efficiency for a LLS installed in Beijing region. The results indicate that: 1) The maximum detecting efficiency of the DF in this system is about 70%; 2) The interference signal can lower the DF detecting efficiency. |
