Abstract：The static shift of MT exploration is the issue concerned by domestic and foreign experts,and many correction meth-ods were proposed.But each method has its advantages and disadvantages.In this paper,the static shift of MT and its deriva-tive methods is discussed from the basic theory,and a joint correction method is proposed using the improved plane Hanning window weighting and the first branch coincidence methods.The optimal estimation and iterative methods are used to combine the correction methods for static shift problems with different formations,and the correction method is consummated for reali-zing large-scale data processing.The correctness of the correction method is verified using the synthetic sounding.And the ef-fectiveness is verified by the comparison of the application results with real data and priori information.
