Prestack migration method, based on wave motion equation, is also developed for receiver function, and compared with ray method. both p - to - s conversion wave and direct p phase contained in receiver function are migrated and imaged by reverse - time migration for data gather including all receiver functions recorded in all seismological stations for one event, and imaging profile is finally obtained by stacking for all events
本文還在接收函數射線反投影疊加成像的基礎上,提出了一種基於波動方程的接收函數疊前偏移成像方法,將同一事件接收函數中的轉換波和直達p波震相以各自的速度向深度方向逆時延拓成像,並通過不同慢度接收函數的疊加,得到最終的偏移成像結果。
