For the notch frequency resulted from the singing interference of the exploration data acquired by the o- cean bottom cables, the processing technique of sensor combination is adopted. Due to the different physical mech- anisms of the pressure sensor and velocity geophone, the received polarities of the interference are still on the con- trary, even in the same location. After processed by the key methods for these two kinds of data: consistency pro- cessing, signal-noise-ratio improving processing, deconvolution processing, selecting suitable means to process combinedly etc, the interference is effectively rejected and the resolution of the above data is enhanced.
