Sampled data lightning strike detection and mapping system capable of early detection of an invalid strike from sampled data and quick resumption of monitoring an incoming signal

摘要

A sampled data lightning strike detection and mapping system receives a signal waveform representative of a lightning strike and digitizes samples of the waveform to generate a train of digital data samples. The digital data samples are monitored to identify a trigger sample which exceeds a predetermined threshold. The trigger sample governs the commencement of processing of digital samples of the train for detection and mapping of the lightning strike. Upon determination of an invalid lightning strike from the digital data samples, the processing is aborted and the monitoring operation resumed until a next trigger sample is identified.
