Stand for research of radio emission of a long electric spark

On the created stand, in laboratory conditions, various phases of discharge development characteristic of lightning were simulated using an electric spark in a long air gap. With the help of special radio equipment, the radio emission of a long electric spark was investigated. It is found that at the stages of development of a spark discharge, radio emission is recorded in a long interval up to at least a frequency of 1.4 GHz. Data on radio emission in this range are of great practical importance for such areas as radio communication (during thunderstorm activity), radar, lightning direction finding.
