摘要：
The adaptive subtraction in surface-relative multiple elimination (SRME) process may distort primaries. Therefore we put forward in this paper an inversion method which overcomes this limitation of SRME. First we introduce the theory of surface-relative multiples elimination based on the sparse inversion, and derives updating formulas of impulse response and signature. Then, we use synthetic data to compare the effectiveness of the estimation of primaries on sparse inversion (EPSI) with SRME for surface-relative multiples elimination. Finally, effectiveness of EPSI is demonstrated on field data. ©, 2015, Science Press. All right reserved.
