单程声波波动方程可以通过双程波动方程在傅里叶域的本征值分解推导,此种解法显式地引入震源项和自由界面边界条件。本文提出的这种单程波动方程的形式对地震反射模拟很合适,因为这样可以把在
The one-way acoustic wave equation can be derived from the eigenvalue decomposition of the two-way wave equation in the Fourier domain. This solution explicitly introduces the source term and the free boundary condition. The form of this one-way wave equation proposed in this paper is suitable for seismic reflection simulations,
