2024-12-30 Wideband Electromagnetic Pulse Detector (WEMPD) example waveforms, physical parameters, and global geographical distributions doi:10.57760/sciencedb.19077 en Abstract: This data set contains two types of WEMPD data. 1) The first are time domain waveforms of three events with the sample band of 25—75 MHz and the sample rate of 160 MHz. 2) The second type is physical parameters, and global geographical distributions of WEMPD events.Data set 1:Consists of three files. Each file contains a header with the WEMPD event time in UTC+8, the sample band of 25—75 MHz, the sample rate of 160 MHz, the sliding window 320 samples, and the sliding step size 304 samples. Data following the header are time-frequency distribution of the electric field in 10log10(V2/m2/Hz).Filenames are:WTIPP_waveform_20231116_073826.784289706.xlsxNTIPP_waveform_20230923_071911.320368156.xlsxNTISP_waveform_20230731_174408.358741681.xlsxData set 2:Consists of three files. Filenames are:WTIPPs_physical parameters_locations.xlsxNTIPPs_physical parameters_locations.xlsxNTISPs_physical parameters_locations.xlsxWTIPPs and NTIPPs have the same header file.
