| 摘 要： | 利用照明分析设计观测系统,可以避免常规观测系统设计中因地下介质均匀假设带来的误差。对波动方程正演算法中的单程波方法进行了近似,提出了一种适合三维复杂介质且面向目标区域的快速波场延拓算法,可以直接对目标区域进行照明分析,无需从地表逐层延拓,计算精度与常规单程波方法相当。通过三维模型进行检验,证明了该方法的可行性。

| 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. |
