DOI: 10.1109/tgrs.2022.3168582
Abstract: Reverse-time migration (RTM) has the particular capacity for complex geological structure imaging. However, massive storage and high computational costs caused by conventional cross-correlation imaging conditions restrict the large-scale application of RTM. The excitation amplitude imaging… read more here.
