Provided is seismic imaging system, particularly, reverse-time migration for generating a real subsurface image from modeling parameters calculated by waveform inversion, etc. A seismic imaging system includes: a logarithmic back-propagation unit configured to back-propagate a ration of a logarithmic measured wavefield to modeling wavefield; a virtual source estimating unit configured to estimate virtual sources from a sources; and a first convolution unit configured to convolve the back-propagated measured data with the virtual sources and to output the results of the convolution.
