Abstract :
As one of the most serious natural disasters, lightning disaster does significant harm to urban civilization. Lightning location system (LLS) detects natural lightning and obtains various kinds of spatial and physical parameters in real time, which provides basis information for lightning study and disaster prevention and mitigation. This paper elucidated the influence of time error on location accuracy in a lightning location network using TDOA method. Related computing method and error distribution law were discussed, which could be used in data processing and accuracy estimation for the improvement of the lightning location accuracy. The results can guide construction of detection network and facilitate determination of location technical index.
