Through-the-Wall Microwave Imaging: Forward and Inverse Scattering Modeling

On the Forward Scattering of Microwave Breast Imaging

Microwave imaging for breast cancer detection has been of significant interest for the last two decades. Recent studies focus on solving the imaging problem using an inverse scattering approach. Efforts have mainly been focused on the development of the inverse scattering algorithms, experimental setup, antenna design and clinical trials. However, the success of microwave breast imaging also he...

An Improved Forward Scattering Simulation Technique for Microwave Breast Imaging

Microwave imaging is a promising alternative to conventional mammography methods. At microwave frequencies, normal and malignant tissues show high contrasts in their electrical properties. Microwave Imaging (MWI) systems can be used to construct three-dimensional profiles of the electrical properties of the body part that is being examined. MWI systems illuminate the body part with electromagne...

An Improved Time-Reversal-Based Target Localization for Through-Wall Microwave Imaging

Recently, time reversal (TR) method, due to its high functionality in heterogeneous media has been widely employed in microwave imaging (MI) applications. One of the applications turning into a great interest is through-wall microwave imaging (TWMI). In this paper, TR method is applied to detect and localize a target obscured by a brick wall using a numerically generated data. Regarding this, i...

Wideband Printed Antenna Elements for Through- Wall Microwave Imaging Applications

In this paper, the probefed stacked patch antenna and the E-shaped patch with a parasitically coupled selfcomplementary element (ESCE) are designed and analyzed in wall proximity in order to study the effects of various wall parameters on the antenna’s radiation characteristics. In particular, the effect of different wall-antenna separations as well as different wall material properties on impe...
