小波分析与电磁测深中静态效应的识别、分离及压制

WAVELETS ANALYSIS AND THE RECOGNITION,SEPARATION AND REMOVAL OF THE STATIC SHIFT IN ELECTROMAGNETIC SOUNDINGS

用小波分析的原理分析频率域电磁测深中的静态效应，给出识别、分离和压制静态效应的新方法．并用理论模型和实例说明方法的效果，该方法还适合对其它类型复杂信号的分析与处理．

In this paper,the static shift is analyzed by using the method of wavelets analysis,and then,we provide a new method to recognize、separate and remove the static shift.Finally,we show the effects of the new method by using theoretical models and the pratical data in CSAMT. Our method is also suited to process other kinds of geophysical signals.
