Abstract

Plane-wave least-square reverse time migration (PLSRTM) delivers high quality images but costs less computation compared with conventional least-square reverse time migration. However, a number of plane-waves are necessary for crosstalk suppression. The paper introduces source polarity encoding to the plane-waves to reach better suppression to crosstalk. Combined with randomized sampling approach, the computation cost of PLSRTM can be decreased a lot. Numerical tests on SEG rugged topography model verifies that the combination with source polarity encoding and randomized sampling can obviously improve the imaging result and computation cost of PLSRTM.
