Real-time microwave imaging of unknown anomalies via scattering matrix
Won-Kwang Park
We consider an inverse scattering problem to identify the locations or shapes of unknown anomalies from scattering parameter data collected by a small number of dipole antennas. Mo…
Analysis and improvement of direct sampling method in the mono-static configuration
Sangwoo Kang, Marc Lambert, Won-Kwang Park
The recently introduced non-iterative imaging method entitled \enquote{direct sampling method} (DSM) is known to be fast, robust, and effective for inverse scattering problems in t…
Direct sampling method for retrieving small perfectly conducting cracks
Won-Kwang Park
In this paper, direct sampling method is considered for determining the location of a set of small, linear perfectly conducting cracks from the collected far-field data correspondi…
Direct sampling method for imaging small anomalies: real-data experiments
Won-Kwang Park, Kwang-Jae Lee, Seong-Ho Son
A direct sampling method (DSM) is designed herein for a real-time detection of small anomalies from scattering parameters measured by a small number of dipole antennas. Applicabili…
Direct sampling method for imaging small dielectric inhomogeneities: analysis and improvement
Sangwoo Kang, Marc Lambert, Won-Kwang Park
The direct sampling method (DSM) has been introduced for non-iterative imaging of small inhomogeneities and is known to be fast, robust, and effective for inverse scattering proble…
Detection of small inhomogeneities via direct sampling method in transverse electric polarization
Won-Kwang Park
Various studies have confirmed the possibility of identifying the location of a set of small inhomogeneities via a direct sampling method; however, when their permeability differs…
