A system for determining the locations of nearby lightning strikes from electric-field and acoustic measurements has been developed and built. The system includes at least three receivers, each equipped with an antenna and a microphone. For each strike, the system measures the difference between the times of arrival of the electric-field and sonic (thunder) pulses at each receiver, computes the distance of the strike from the time difference and the speed of sound (about 320 m/s), then uses the distances to determine the location of the strike. The basic concept of this system is thus a variant and extension of the time-honored concept of estimating the distance of a lightning strike from the difference between the times of arrival of the visible flash and the audible thunder.
