Abstract: The seismometer pattern layout design with illumination analysis can avoid the errors from hypothesis of homogeneous media in its conventional system design. The approximated analysis of one-way wave method in forward algorithm of wave equation is conducted, and a quick wave-field continuation algorithm for 3-D complex media and target-oriented area is proposed to directly make an analysis of target area without bed-by-bed continuation from the surface. The precision of this method is similar to the conventional one-way wave method. The verification of 3-D model indicates that this method is feasible.

Key words: seismometer pattern layout, wave field continuation, one-way wave, illumination analysis
