| Popis: | International audience; The development of methods and tools for the roadinfrastructure sustainable management is a research challenge,especially for nondestructive testing methods. This letter focuseson the estimation of the thickness of civil engineering structures,like pavements, and more precisely, the time delay and interfaceroughness. We propose a modified Min-Norm algorithmwhich allows efficiently estimating the time delay and interfaceroughness without the eigenvalue decomposition. Therefore, it hasa smaller computational load compared with subspace-basedmethods. The experimental results show the efficiency of theproposed algorithm. |
