摘要
Abstract
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 method has well performance on positioning accuracy and reliability, and can meet the requirements of real-time lightning location.关键词
