The simultaneous source technology has become popular since it can provide a better image much more efficiently. It can effectively improve the efficiency of acquisition by reducing the range of random delay between single source in mixed source, however, it may also bring some negative effects on the deblending of the mixed data. The blending noise contained in non-common-source domain data will be much more concentrated after pseudo-separation, which is difficult to suppress. The trilateral filter, an improvement of the bilateral filter, is based on the ROAD (rank ordered absolute difference). This paper deblends the simultaneous source seismic data based on the trilateral filter. Compared with the multilevel median filter, we can achieve good results by using both two filter when the random delay time range is large, however, when the random delay time range is small, the method presented in this paper can be more effective, and besides, it can also retain more detail information.
