论文摘要
由点源触发的不均匀波方程构成了地震反转的最现代计算技术的基础。在这项工作中，我们建议将不均匀的波方程转移到均匀方程中。我们表明，一个人可以从不均匀方程中抑制基于小波的源项，以将波场的初始时间派生条件设置为相同类型的缩放小波。使用均匀的波方程，可以稍微降低数值建模的计算成本。
The inhomogeneous wave equation, triggered by point sources, forms the basis for the most modern computational techniques of seismic inversion. In this work, we propose to transfer the inhomogeneous wave equation into a homogeneous equation. We show that one can suppress the wavelet-based source term from the inhomogeneous equation in favour of setting the initial time derivative condition of the wavefield as a scaled wavelet of the same type. With the homogeneous wave equation, one can slightly reduce the computational cost of numerical modeling.
