Abstract

This article presents an imaging technique to locate a weak perturbation in a multiple scattering environment. We focus on concrete probed by ultrasound. We derive a formula to predict the spatiotemporal decorrelation of diffuse coda waves induced by an extra scatterer. We solve the inverse problem with a maximum likelihood approach. Using elastic waves in the 50-400 kHz frequency band, we recover the position of millimetric holes drilled in a concrete sample with a precision of a few centimeters.
