Abstract
Imaging of lightning channel in three dimensions is realized by UHF interferometer observation at two stations. These interferometers are operating at the center frequency of 327MHz and the time resolution of 1μs. The three dimensional observation is carried out at Darwin, Australia in November 1996 and we perform accurate calibration in order to obtain clear lightning images in three dimensions. This paper shows imaging results of progression of a negative leader and subsequent dart leaders of multiple-stroke flashes. This paper presents case study of multiple-stroke flashes and comparative study between discrete and hybrid flashes. The analysis shows the evidence that the system is able to locate lightning channels in three dimensions and the advantage of three dimensional analysis using interferometers.
