Bifocusing-Based Imaging of Small Penetrable Dielectric Objects From Fresnel Dataset

Sangwoo Kang;Minyeob Lee;Won-Kwang Park;Seong-Ho Son

IEEE Transactions on Antennas and Propagation
Year: 2025 | Early Access Article |
The bifocusing method (BFM) is one of the most effective non-iterative techniques for recognizing the existence and outline shape of a set of objects. In most previous studies, the BFM was designed under the assumption that complete elements of the multi-static response (MSR) matrix are collectable. Unfortunately, in the setup in some laboratory-controlled experiments, it is impossible to collect ...Show More

Fast Anomaly Detection via the Orthogonality Sampling Method in Microwave Imaging

Sangwoo Kang;Seongje Chae;Won-Kwang Park

2022 IEEE International Symposium on Radio-Frequency Integration Technology (RFIT)
Year: 2022 | Conference Paper |
We consider an application of the orthogonality sampling method (OSM) for a fast identification of a small anomaly from scattering parameter data. In this study, we cannot measure the scattering parameter data when the location of transmitting and receiving antenna is same. Due to this reason, we set the unknown data as a constant and design a new indicator function of the OSM with multiple source...Show More

Single- and Multi-Frequency Direct Sampling Methods in a Limited-Aperture Inverse Scattering Problem

Sangwoo Kang;Marc Lambert;Chi Young Ahn;Taeyoung Ha;Won-Kwang Park

IEEE Access
Year: 2020 | Volume: 8 | Journal Article |
Cited by: Papers (19)
Although the direct sampling method (DSM) has demonstrated its feasibility and robustness for imaging of small inhomogeneities, mathematical analyses of DSM have been conducted only on the full-aperture inverse scattering problem. Numerous studies have shown that DSM can also be applied in the limited-aperture inverse scattering problem, but most of its applications are still heuristic. This study...Show More

Analysis and Improvement of Direct Sampling Method in the Monostatic Configuration

Sangwoo Kang;Marc Lambert;Won-Kwang Park

IEEE Geoscience and Remote Sensing Letters
Year: 2019 | Volume: 16, Issue: 11 | Journal Article |
Cited by: Papers (12)
The recently introduced noniterative imaging method entitled “direct sampling method” (DSM) is known to be fast, robust, and effective for inverse scattering problems in the multistatic configuration but fails when applied to the monostatic one. To the best of our knowledge, no explanation of this failure has been provided yet. Thanks to the framework of the asymptotic and the far-field hypothesis...Show More

Alternative Direct Sampling Method in 3D Inverse Electromagnetic Scattering Problem

Sangwoo Kang;Marc Lambert

2018 International Symposium on Antennas and Propagation (ISAP)
Year: 2018 | Conference Paper |
In the following the recently developed direct sampling method for solving 3D inverse electromagnetic scattering problem is dealt with and an alternative indicator function decreasing the artifacts is proposed. The latter is an extension of an alternative direct sampling method recently proposed for 2D inverse acoustic case. Due to the vectorial aspect of the 3D problem the imaging test functions ...Show More

Analysis of Kirchhoff Migration and Direct Sampling Method within Far-Field Approximation: From the Multi-Static to the Mono-Static Configuration

Sangwoo Kang;Marc Lambert;Won-Kwang Park

2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC)
Year: 2018 | Conference Paper |
A recently developed direct sampling method (DSM) is studied in the framework of multi- and mono-static configurations within the far-field hypothesis. A full analysis of the behavior of the DSM has not been provided yet in both cases even if, due to a lack of information compared to multi-static data, the mono-static configurations need an adapted analysis. Thanks to the theoretical analysis base...Show More

Comparing the imaging performance of MUSIC and Linear Sampling method

Sangwoo Kang;Won-Kwang Park

2016 9th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI)
Year: 2016 | Conference Paper |
Cited by: Papers (1)
The MUltiple SIgnal Classification - MUSIC - algorithm and the Linear Sampling - LS - method are fast, stable, and effective non-iterative imaging techniques in inverse scattering problem. In fact, some previous studies indicated that the linear sampling method is an extended version of MUSIC. However, numerical results in support of this assertion have not been provided. In this contribution, we ...Show More
