Coherent interferometric Imaging (CINT) in concrete.

Waves are been used for the detection and imaging of objects for many years. We all know the radar, which uses electromagnetic waves, the sonar that is based on acoustic waves, and medical ultrasound. In most of these applications the materials encountered in practice are often complex and their properties are not known - and cannot be estimated - in every detail. We, therefore, model the propagation medium as a random process for which we know some statistical properties. Our goal is to solve the imaging problem in a regime where multipathing due to the heterogeneities is important. The challenge is to produce reliable, i.e., statistically stable, results, especially when there is no a priori knowledge about the propagation medium.
