1. A method for deblending seismic data associated with a subsurface of the earth, the method comprising:
receiving an input dataset generated by source excitations of first and second sources S1 and S2; receiving source excitation times for the first source S1 and the second source S2; applying, with a computing system, an annihilation filter to the input dataset, using the source excitation times for the first source S1, to estimate a data sub-set relating to the second source S2; convolving the data sub-set with an operator to form a signal estimate associated with the second source S2, using the source excitation times of the first and second sources S1 and S2; and generating an image of the subsurface, based on the signal estimate associated with the second source S2, to identify geophysical structures, wherein the annihilation filter removes coherent energy while a coherency filter removes incoherent energy. |
