Abstract

Since 1996, KEPCO has been operating a wide range lightning detection system, LPATS, and been accumulating relative application techniques and statistical analysis skills. So, KEPRI already has its own basis to develope more accurate advanced detection technology and references to do comparative study. For three-dimensional imaging of lightning channels, UHF/VHF antenna systems were installed at 2 sites. The distance between two sites is about 30 km. These systems were used the AOA(Angle of Arrival) methods for lightning detection. In this paper, we would like to introduce about our system and its results.
