Multiple Scattering Suppression in Heterogeneous Media: High‐Precision Imaging of Sleeve Grouting Defects Based on Elastic Reverse Time Migration

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an elastic wave reverse time migration (RTM) method to suppress multiple scattering noise in heterogeneous concrete. By effectively utilizing scattered wavefields, RTM enables high‐precision, robust imaging of sleeve grouting defects in prefabricated buildings, significantly outperforming traditional algorithms.
