闪电定位误差及探测效率评估

为了实现闪电定位中定位误差及探测效率评估的自动化,从时差法闪电定位原理出发,分析了闪电定位原理存在的问题及其定位的误差来源。采用计算机模拟的方法,实现了对闪电的定位误差及探测效率的定量评估。以安徽省闪电定位网为例,说明了利用评估软件可以对已有的闪电定位网络作出有效的定位误差评估。分析了几种不同几何分布的布站效果,给出了几种基本布站模型,为将要布设的闪电定位网布站方案的提出提供选址依据。

Evaluation of error in lightning orientation and lightning detection efficiency

In order to realize automation in evaluation of the error and detection efficiency in lightning orientation,based on the principle of TOA lightning orientation,the problem in lightning orientation and its error source were analyzed,and a software developed to evaluate the error in lightning orientation and lightning detection efficiency.With this software,the orientation error and detection efficiency of lightning orientation net can be evaluated,no matter whether it already exists or in the planning.Taking the lightning orientation net in Anhui province for example,the existing lightning orientation net could be evaluated with this software.Several net models with different station geometrical places were discussed.The results can help us select the place for new detection station.
