Investigation of Short Base Line Lightning Detection System by Using Time of Arrival Method
Lightning locating system is very useful for the purpose of giving exact coordinates of lightning events. However, such a system is usually very large and expensive. This project attempts to provide instantaneous detection of lightning strike using the Time of Arrival (TOA) method of a single detection station (comprises of three antennas). It also models the whole detection system using suitable mathematical equations. The measurement system is based on the application of mathematical and geometrical formulas. Several parameters such as the distance from the radiation source to the station and the lightning path are significant in influencing the accuracy of the results (elevation and azimuth angles). The signals obtained by all antennas were analysed using the LabVIEW software. Improvements in the lightning discharge locating system can be made by adopting a multi-station technique instead of the currently adopted single-station technique.
