中文摘要：

目前基于雷声的三维定位系统多停留在实验阶段,从业务化运行的角度考虑,改进了单站式闪电三维定位系统的麦克风阵列,设计了定位算法,利用该系统采集了2014年夏季南京地区的部分闪电数据,并从计算耗时的角度对三维通道实时定位的可行性进行了研究。结果表明,基于声光信号的单站式闪电三维通道定位系统可重构闪电的三维通道;对连续的雷声信号进行分帧,帧长取0.03 s时,声源定位点可描绘出清晰的闪电主通道;采用分组保存和处理闪电声光信号的方法,可实现实时定位,当一组数据的保存时间为50 s时,计算耗时为46.507 s。

英文摘要：

Considering business needs, an improved microphone array structure of three-dimensional lightning channel of single station and its related algorithms are presented in this paper. The system was used to collect part of the lightning data in Nanjing in the summer of 2014, and then the feasibility of re- al-time positioning of the three-dimensional lightning channel is studies from a time-consuming opearation viewpoint operation is studied. Results show that the three-dimensional lightning channel positioning sys- tem of single-station based on acoustic and optical signals can reconstruct the channel of lightning ; when the continuous signal turns into frames and the frame length is set to 0. 03 s, the sound positioning point can depict the main channel of lightning clearly; storage and processing of the grouping data of thunder and flash signals can achieve real-time positioning, when the time length of preservation is 50 s, and the time-consuming of computer is 46. 507 s.
