Common Reflection Surface stack is a brand-new and special ZO imaging method, the theory of CRS stack stems from paraxial ray theory, the biggest difference between CRS stack and conventional ZO imaging method is that it consider a reflector R as a circular reflector segment Cr placed in the vinicity of reflector R, Cr can be seen as the second order approximation of the reflector. The CRS traveltime surface is the multi-coverage reflection response of the reflector mirror assigned to R.
共反射面元(CommonReflection Surface=CRS)叠加技术是一种全新的、特殊的零偏移距剖面成像方法,CRS迭加理论源于傍轴射线理论,它与普通的零偏移距剖面成像方法的最大区别是它认为地下反射层是由许多个小反射弧段互相叠合组成的,认为来自某反射点附近的一个邻域内的反射信息都可以对该反射点的成像作出贡献,因此对该反射点进行零偏移距成像时就应该聚焦更多的能量参与迭加。
