DOI: 10.1109/tgrs.2024.3400309
Abstract: Ground-penetrating radar (GPR) is a nondestructive near-surface geophysical detection method, which is often used to locate subgrade diseases in railway subgrade detection. However, the strong noise reflected by the sleeper will obscure the effective information… read more here.
