Abstract

The electromagnetic detection of buried objects is addressed in this paper, where a three-loop iterative imaging technique is proposed. A quantitative solution of the nonlinear inverse scattering problem is obtained by integrating a multiscaling strategy with a multifrequency inexact-Newton technique formulated in L p spaces. Numerical results, where ground penetrating radar measurements have been simulated by a finite-difference time-domain method with various levels of data noise, demonstrate the advantages of the proposed strategy.
