Phys.org  September 12, 2023 Despite some advances in existing observational techniques, scientists have continued to strive for higher accuracy in analyzing the complex phenomenon of lightning. To improve the accuracy and resolution of lightning observations researchers at the New Mexico Institute of Mining and Technology optimized the very-high-frequency signal from the interferometer using the double-sided mirror and ensemble empirical mode decomposition method to perform quality control and band-pass truncation on the raw signal. By combining the main window with the auxiliary window, they achieved waveform matching of signals from different antennas based on the generalized cross-correlation method. They obtained the […]
