Abstract:To recognize the magnetic storms automatically from the horizontal component
of geomagnetism, a combined method of magnetic storms recognition based on Fisher and kernel Fisher discriminant analysis is presented. The data used in the study are derived from Ming tombs of Beijing geomagnetic station. In the case of the little number of the data samples, the average rate of this combined method for magnetic storms recognition is above 85%, and the recognition rate will be improved by the increasing amount of data samples.
