Pengukuran Radiasi Elektromagnetik Frekuensi Sangat Tinggi (VHF) Petir Compact Intracloud Discharges

Primas Emeraldi, Ariadi Hazmi


Compact Intracloud Discharges (CIDs) are another type of intracloud lightning. CIDs emit strong high-frequency emissions compared to the first return stroke from cloud to ground lightning or other types of discharge in clouds. High-frequency radiation from lightning CIDs may affect electronic systems, which may pose a danger to communications equipment, radio, satellite and avionics systems. This paper presents a design of a fast electric field detector to detect a broadband of radiation from CIDs and Very High Frequency (VHF) electric field detector to detect high-frequency radiation of CIDs. Fast electric field detector circuit consists of buffer circuit and integrator amplifier while VHF electric field detector is a buffer circuit and active band pass filter at 51.76 MHz. From the measurement of the electric field of lightning during March 2016 to March 2017, 104 CID negative lightning data and 33 positive CID lightning data was recorded. VHF radiation of CID is detected simultaneously with the occurrence of CID lightning events. The VHF radiation of negative CID and positive CID have similar time characteristics.
