LIGHTNING STRIKE DETECTION AND MAPPING SYSTEM |
摘要 |
A lightning strike detection and mapping system which determines the range and bearing of each valid lightning strike by (1 ) computing the Fourier Transform, and more preferably the discrete Fourier Transform (DFT) of the X and Y waveforms, classifying the lighting strike based on the DFTs, and estimating the range of the lightning strike based on a type-dependent weighted sum of the DFT coefficients; (2) detecting whether the X or Y waveform is a doublet waveform and classifying the lightning strike based on the detection of a doublet; (3) performing range correction based on type classification and tail activity; and (4) reconstructing clipped waveforms in order to extend the dynamic range of the system.
