摘　　要：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以及其定位的误差来源。利用非线性最小二乘法进行优化计算,采用计算机模拟的方法,实现了对西昌卫星发射中心所使用的ADTD闪电定位系统的定位误差评估。研究成果不仅可以评估已设探测网络的定位误差,而且可为布设站点提供选址依据,提高探测精度。In order to automatically evaluate the precision and efficiency of lightning positioning system in Xichang Satellite Launch Center （XSLC）, lightning positioning principle and source of errors for the positioning are analyzed by using time difference lightning positioning principle. By means of nonlinear least square method to optimize calculation and utilizing computer simulation approach, effective evaluations on the positioning errors for the ADTA lightning positioning system used in XSLC are realized. The products can be used to provide site choosing information for setting up stations and improving detection precision, as well as used to evaluate the errors of lightning positioning systems.
