An Improved Method for Analyzing Broadband VHF Interferometer Lightning Observations

Based on the very-high-frequency (VHF) pulse signal detected by interferometer (INTF) antennas as the reference unit, a lightning location method based on pulse matching and peak extraction is proposed in this article. The first key step of this method is to optimize the raw VHF data of the INTF by...
