摘要
简述了闪电VHF辐射源窄带干涉仪定位原理及其数据处理方法,利用改进的窄带干涉仪系统对闪电先导VHF辐射源进行定位,给出了闪电放电通道的时空结构,并结合电场变化资料和声光差记录,估算了闪电先导放电发展的速度.
The theory and method of data processing of lightning location system,narrowband interferometer were introduced.Using the improved narrowband interferometer,the whole progression process in time and space of a lightning flash could be reconstructed.The discharge speed of lightning leader was estimated with the data of electric field change and the difference between light and sound of lightning.
