Evaluation of the concrete electromagnetics properties by using radar measurements in a context of building sustainability

In this paper, an inverse method to evaluate the dielectric values of concrete sample by using radar measurements in the context of the building security is presented. A numerical model of the experimental device is proposed and compared with the data measured. By using this numerical model, a convergent optimisation strategy using a Gauss–Newton method is given. This optimisation process is applied on simulated data and on several configurations using measurements.
