Abstract
A sampled data lightning strike detection and mapping system receives a signal waveform representative of a lightning strike and samples the waveform to generate a train of data samples representative thereof. A data sample of the train is identified as exceeding a predetermined threshold and designated as the trigger sample. The system recovers a predetermined number of data samples, preceeding the trigger sample, of the train for processing to detect and map the lightning strike.

A sampled data lightning strike detection and mapping system comprising:
- receiving means for receiving a signal waveform representative of a lightning strike;
- sampling means for sampling said signal waveform to generate a train of data samples representative thereof;
- identifying means for identifying a data sample of said train which exceeds a predetermined threshold level as a trigger sample;
- recovering means for recovering a predetermined number of data samples, preceeding said trigger sample, of said train based upon said trigger sample;
- and
- means for processing the recovered predetermined number of data samples to detect and map the lightning strike.
A sampled data lightning strike detection and mapping systems comprising:
- receiving means for receiving a signal waveform representative of a lightning strike;
- sampling means for sampling the received signal waveform and for digitizing said samples to generate a train of digital data samples;
- digital signal processing means operative to process the digital data samples of said train for identifying a sample which exceeds a predetermined threshold level as a trigger sample;
- and
- recovering means for recovering a predetermined number of digital data samples, preceeding the trigger sample, of said train based upon said trigger sample, for lightning strike detection and mapping processing thereof by the digital signal processing means.
A sampled data lightning strike detection and mapping system comprising:
- receiving means for receiving first and second signal waveforms representative of a lightning strike;
- sampling means for sampling said received first and second signal waveforms and for digitizing the samples to generate a first train of digital data samples representative of the first signal waveform and a second train of digital data samples representative of the second signal waveform;
