摘　　要：甚高频短基线时差法雷电定位系统是当前雷电定位系统研究的一个热点问题。用先导通道上足够多个辐射点源代替连续的先导通道,计算了短基线时差法雷电定位系统的方位角和仰角误差。研究发现,方位角误差较小,而仰角误差较大。方位角和仰角误差随距离的增大而减小,但方位角和仰角误差随基线长度的增加而增加。闪电通道分叉时或者为曲折放电路径时,方位角和仰角误差与分支通道位置和曲折方向有关。Very high frequency lightning locating systems based on time difference of arrival and short baseline configuration are research hotspots in studying lightning locating technique.The continuous leader path is substituted by plenty of point radiation sources,and the azimuth and elevation angles of short baseline time difference of arrival lightning locating systems are calculated.It is shown that the errors of azimuth angles are small,and the errors of elevation angles are comparatively larger.Both the errors of azimuth and elevation angles decreased as the distance increased.However,both the errors of azimuth and elevation angles increased as the baseline length increased.When considering the branches and twists of lightning paths,the errors of azimuth and elevation angles are related to the position of the branches and the orientation of the twists.
