大地电场数据频谱分析及幅值提取软件的研发

Development of the Software for Spectrum Analysis and Amplitude Extraction of Geoelectric Data

通过分析大地电场观测数据存储的特点与规律,利用Matlab语言研发本软件。利用此软件可对大地电场数据进行分段频谱分析,并形成文本数据文件,以及提取各时间段日波、半日波等频率幅值,方便工作人员和分析研究人员掌握大地电场的频谱及其随时间的变化规律,为地震前兆现象的分析研究提供帮助。同时,此软件也可作为模板,经适当修改后,采用不同的数据分析方法来处理其他仪器的观测数据。

By analyzing the features and law of data storage of geoelectric field,an software is developed with Mablab.The software can make spectrum analysis of geoelectric data and output results in text fomat The software also has functions to extract amplitudes of daily wave and semidiurnal wave according to your selected time,which will be helpful for researchers to look over the variation of geoelectric spectrum and its variation with time and study the earthquake precursors.In addition,with some modifications,this software can be taken as a template to process the data of other instruments with another analysis methods.
