Abstract:Lightning whistlers,found frequently in electromagnetic satellite observation,are the important media to study the plasmasphere of the earth space.With the increasing number of data observed from electromagnetic satellites,a considerable amount of time and human efforts are needed to detect lightning whistlers from these tremendous data.However,in recent years,with the development of artificial intelligence(AI)technologies such as computer vision and deep learning,algorithms for lightning whistlers automatic detection in the time-frequency profile of the electromagnetic satellites data have been conducted.This study analyzes and summarizes the existing automatic detection algorithms.Firstly,we describe the time-frequency characteristics and types of lightning whistlers recorded by electromagnetic satellites.Secondly,we introduce the automatic detection technique,which is composed of three steps involving extracting the feature of the object(the lightning whistler or noise),choosing the correct class label for the feature,and providing the boundaries of each object.Then,we analyze and summarize the existing research methods from three aspects including lightning whistler feature extraction,classification and positioning.Thirdly,we briefly describe the metrics to evaluate the mathematical model for automatic detection of lightning whistler.Fourthly,we apply three typical algorithms on the search coil magnetometer data of ZH-1 satellite to detect the lightning whistler automatically and conduct a deep analysis on the results.Lastly,we present existing problems and future possible research directions.
Keywords:Electromagnetic satellites  Lightning whistler  Automatic detection  ZH-1 satellite
