Sparse CL-SRME using impulse response and source wavelet: Method and applications

We proposed a new approach for multiple removal using the CL-SRME method. Instead of directly updating the estimated primaries, we update the impulse response and the source wavelet together during inversion as both are used to defined the primaries estimate. Through imposing the sparsity constraint...
