Lightning location requires high real-time and positioning accuracy,and the grid search algorithm needs a large amount of computation.An optimization method of lightning location based on grid search is proposed.This method quickly searches the candidate target regions by using multi-dimensional spatial data index.Afterwards,comparing the classification error of SVM(Support Vector Machine)classifier which is stored on the target candidate regions for lightning location.Experimental results show that this me...

1引言监测区域闪电发生情况,对雷暴灾害预警具有重要作用[1]。目前,由多个探测站点构成的区域闪电监测网大都采用到达时间差法(Time Difference Of Arrival,TDOA)进行定位[2-4]。当只有两个站点接收到同一闪电信号时,只能确定一条双曲线,需结合磁定向(MagneticDirection Finder
