Abstract

A lightning location system (LLS) is designed to determine the location or estimate of a lightning strike more accurately. It is essential to map areas with high intensity of lightning strikes so that they can be used as a reference in determining protection for specific objects and minimizing losses to both inanimate objects and living things. In this project, the data used is secondary data obtained from the monitoring station for Interferometry lightning activity at Universiti Teknikal Malaysia Melaka (UTeM). The Interferometry method determines the value of the azimuth and elevation angles using the time difference between each Antenna. Lightning data management is done through Matlab software by applying windowing and cross-correlation. To obtain good data, windowing is done with a window size of 128 and an overlap of 16. Cross-correlation is applied to correlate the two signal waves to produce a time delay value for calculating elevation angles and azimuth. As a result, 336 windows were successfully correlated and obtained time delay values so that 336 azimuth and elevation data were successfully plotted on the lightning location map with fluctuating values indicating lightning movement during the lightning strike process.
