In order to improve it,dynamic time shift static correction technique,model simulation velocity analysis and map technique are developed and applied in the area,overall studies for the area carried out by a new thought of the integration of processing and interpretation.

The method of synchroarray magnetoelluric sounding data processing is studied on the basis of the theoretical anaysis of MT curve static shift and other distortions due to surface terrain andnear-surface inhomogeneities.

In the case of static offset resulted by the surface electricity inhomogereity,the static offset could be removed by the phase transfer.

As in other electromagnetic sounding methods,static offset and correction also arise in frequency-domain electromagnetic sounding.
