Summary Ghost wave is a problem which always exists in marine seismic exploration. It has not been fundamentally resolved for a long time and restricts the seismic exploration technology progress seriously. In this paper, we develop a deghosting method based on wavelet processing. The first step is calculating the cable-ghost suppression operator and the source-ghost suppression operator by far field wavelet processing, then we apply the operators to the seismic data to suppress ghost wave. The test result of theoretical model and deepwater seismic data proves that the method is effective to suppress ghost wave; broaden the frequency spectrum; improve the quality of seismic data.
