Abstract

In the smoothing velocity model, wave equation is often used to simulate the wave propagation. The one-way wave is faster than the two-way wave in calculation, higher in accuracy than the ray approximation calculation, and has a wide range of applications. Traditional one-way wave calculation only focuses on its travel time information, and its amplitude does not conform to spherical diffusion principle and energy conservation. Therefore, this paper proposes a one-way wave with amplitude preserving, and finds that the phase information of its one-way wave can be guaranteed through amplitude preserving processing, which is verified by simulation.
