Abstract: Similar with seismic prospecting, there exist multiple and proximity disturbances in magneto-electrotelluric exploration(MTE). To study this problem is an important in geologic interpretation of MTE data. Theoretically, this study analyzed existence of multiple wave in pseudo seismic interpretation of MT,pointed out that no multiple interference appears in the magneto-electrotelluric sounding reflectance functions, and derived mathematical relations between the reflectance function and top proximity interference, giving the way of frequency-selecting for rejection of top proximity interference. Finally, the theoretical model was estimated by using pseudo seismic interpretation of MT and electromagnetic reflectance function continuation imaging methods for indicating effect of the theory.
