【Abstract】 The influence of current leakage from horizontal electric dipole on frequency electromagnetic sounding data was studied in this paper. Analysis and computation results showed that such a influence did not theoretically make Cagniard resistivity distorted, but the amplitudes of electric and magnetic fields were decreased clearly. So the signal to noise ration was also decreased,and the apparent resistivities definded by electrical and magnetic fields respectively were also decreased clearly. Some means to avoid this kind of influence was presented in this paper.更多还原
