| Abstract: | A new lightning locating technology,called Lightning Mapping Array(LMA),has been developed.The system takes advantage of GPS technology to measure the times of arrival(TOA) of lightning impulsive very high frequency(VHF) radiation events at each remote location.The spatiotemporal development processes of lightning are described in three-dimension by measurement of the system with high time resolution(50 ns) and space precision(50-100 m).The charge structures in thunderstorm and their relationship with light... |
