Lightning Location and Mapping System Using Time Difference of Arrival (TDoA) Technique

摘要: Lightning strike is a dangerous natural phenomenon that can cause various problems. Telecommunication subscriber lines (TSLs) and electrical power are two systems almost always affected by nearby lightning strikes. Voltages in the telecommunication line (TSL) do get induced The voltage be carefully measured parameters such as current wave shape, peak locations reproduced. Better designs of protection realised if data on distribution given region known. Commercial mapping or locating based several technologies (Araujo, 2001; Kenneth, 2003). most popular methods those Time Arrival (ToA) Directional Finder (DF) principles. An example system (LLS) ToA method country- wide LLS owned Malaysian national company (TNB). capable determining coordinates cloud-to-ground strikes within 500m accuracy. However, for localised lightning, say 1 square km area, this accuracy too large to meaningful.
