In civil engineering, ground penetrating radar is widely used for road pavement surveys. The layer thickness is deduced from both the time delays of the backscattered echoes and the permittivity of the layers. In this paper, the influence of the interface roughness is studied. A modified ESPRIT algorithm is proposed for estimating the time delay, the interface roughness and the permittivity of layers from the received echoes. The algorithm is tested on simulated data obtained from the propagation inside layer expansion (PILE) method. Numerical examples are provided to demonstrate the performance of the algorithm.
