Abstract
A method for analyzing signal irregularity of radiation in a lightning leader is provided, which relates to a field of lightning signal processing and includes: S1: acquiring electric field signals; S2: dividing the electric field signals into multiple segments according to time, and calculating an average sample entropy value of each segment of the electric field signals; S3: dividing the multiple segments of electric field signals into three regions according to the time, quantifying irregularity of radiation of the three regions in the leader according to sample entropies and performing classification based on numerical variation characteristics of the irregularity; S4: comparing the classified data with lightning positioning data to form an analysis database; and S5: acquiring real-time electric field signals, calculating average sample entropy values of the electric field signals, and predicting development characteristics of irregular radiation in the lightning leader.
