小波变换在大地电磁测深静校正中的应用

Application of Wavelet Transformation of Static Correction in Magnetotelluric Depth Measurement

针对大地电磁测深 (MT)资料处理中存在的静态偏移问题 ,利用小波变换的Mallat算法对实测MT资料进行静校正处理。实测资料的处理结果表明 ,利用小波变换可以进行压制MT中的静态偏移 ,是一种有效的。

ln consideration of the problems of static shift in processing magnetotelluric depth measurement date (MT), Mallat Algorithm of the wavelet transformation is used to statically correct the measured MT data. The result shows that the wavelet transformation would be used to constrain the static shift in MT, which is effective and potential method of static correction.
