带限光线追踪在保持光线追踪框架内的同时，不需要对原始模型进行处理或改变，从而以比传统光线追踪更高的保真度捕捉到与有限差分波传播相当的波运动学。我们给出了使用常规射线跟踪和带限射线跟踪方法获得的基尔霍夫偏移的例子。带限光线跟踪旨在克服标准高频光线跟踪在包含复杂界面的复杂速度模型中的一些限制。
Band-limited ray tracing captures the wave kinematics that are comparable to finite-difference wave propagation with higher fidelity than conventional ray tracing while staying within the ray tracing framework, without requiring processing or alteration to the original model. We present examples of Kirchhoff migration obtained using conventional ray tracing and band-limited ray tracing methods. Band-limited ray tracing aims to overcome some of the limitations of standard high-frequency ray tracing in complex velocity models that contain complex interfaces.
