英文摘要The finite-difference method has been widely utilized in seismic wave numerical modeling, seismic imaging and full waveform inversion. The accuracy of finite-difference numerical solutions directly affects results of seismic imaging and inversion. Using an auto-convolution combined window function to truncate spatial convolutional counterpart of the pseudospectral method, optimized explicit finite-difference operators are derived.
