UWB Signal Processing for the Solving Inverse Scattering Problem of Plane-Layered Media

Abstract

The possibilities of using UWB pulse signals GPR for solving inverse scattering problems, especially in the frequency domain, have been investigated. The proposed computational algorithms are based on previously developed iterative schemes for solving inverse scattering problems by a procedure of minimizing the auxiliary residual functional. To carry out computational experiments the initial data synthesized by software constructing the Green function for corresponding direct diffraction problems are used. The values of electrical and geometric parameters of plane-layer media were chosen primarily based on the specifics of the problems of nondestructive control of road pavements and other building structures, as well as the problems of biomedical research. The obtained results allow to improve the effectiveness of monitoring methods of the road pavements, subbase and subgrade current condition.
