Multicomponent adaptive focused beam migration based on attenuation compensation
This paper extends the adaptive focused beam technique to elastic media.By constructing elastic Green̍s function and incorporating the advantages of adaptive focused beams while accounting for the influence of viscosity on Gaussian beams,we develop a multi-component adaptive focused beam migration method based on attenuation compensation.Model tests verify the correctness and adaptability of this method,demonstrating its ability to handle strong lateral velocity varia-tions,reduce noise impact on imaging results,and produce cleaner,clearer images.
