摘要：Poynting vector is used to decompose source and receiver wavefields into different angle, then the partial images of different incident and scatter angle are computed and local imaging matrix(LIM) can be constructed. LIM composes all the angle information which is related with the geological structure, and it can be used as the base of angle- domain imaging analysis. We used LIM to reverse time migration image in angle domain and geological dip estimate. The numerical example is tested to demonstrate the computation method.
