Abstract
A sampled data lightning strike detection and mapping system receives a signal waveform representative of a lightning strike and other electrical activity and samples the waveform to generate a train of data samples representative thereof. The data samples of the train are processed by a first processor to detect the lightning strike and estimate a location thereof. A predetermined number of data samples of the train are processed by a second processor to generate a plurality of frequency signals representative of a frequency spectrum of the processed data samples. The system includes a display which is driven by the first processor to display an indication of the lightning strike based on the estimated location thereof and further driven by the second processor to display a representation of the frequency spectrum. In a preferred embodiment, the first and second processors are embodied in a common signal processor.
