Without phase information of the measured field data, the phaseless data inverse scattering
problems (PD-ISPs) counter more serious nonlinearity and ill-posedness compared with full …

An innovative inverse scattering (IS) technique for the simultaneous processing of
multifrequency (MF) ground-penetrating radar (GPR) measurements is proposed. The …

The application of the compressive sensing (CS) paradigm to retrieve non-single-pixels
contrast profiles is discussed. By exploiting a wavelet representation to model complex …

Ground-penetrating radar (GPR) technology for underground exploration consists of the
transmission of an electromagnetic signal in the ground for sensing the presence of buried …

We present a contrast source inversion (CSI) algorithm using truncated wavelet
representations. Specifically, we represent the unknown contrast sources and the contrast …

In this article, a hierarchical stochastic optimization algorithm for profiling of multiple high-
contrast buried objects in large investigation domains (IDs) is presented. As this problem is …

Purpose The authors investigate the impact that incremental increases in the level of detail
of patient‐specific prior information have on image quality and the convergence behavior of …

In this paper, the quantitative imaging of the dielectric characteristics of unknown targets
buried in a lossy half-space is performed by suitably processing wide-band ground …

The application of a multiscale strategy integrated with a stochastic technique to the solution
of nonlinear inverse scattering problems is presented. The approach allows the explicit and …

A microwave characterization technique to inspect subsurface scenarios is proposed and
numerically assessed in this paper. The approach is based on a combination of finite …
