Imaging Complex Salt Bodies with True Amplitude Turning Wave One-Way Wave Equation

摘要：

The conventional one-way wave equation migration only computes wavefields with propagation angles less than 90°. Therefore, steeply dipping reflectors are often absent from its images. In this at, we propose a modified version of one-way wave equation migration which incorporates true amplitude corrections to enhance steep dips and propagates wavefields to any possible direction. With this new method, turning waves can be properly imaged and the imaging capability of one-way wave equation is greatly improved.
