Microwave Imaging Using SAR
Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
متن کاملImaging visible light using anisotropic metamaterial slab lens.
It has been shown that an anisotropic metamaterial made of nanowire array can realize negative refraction of light even without a negative phase index of refraction. Such non-resonant bulk material can be fabricated by bottom-up electrochemical method. Using this material, we were able to achieve lensing action with micron-thick slab and demonstrate imaging of a slit object. The details of the ...
متن کاملMicrowave Imaging Sensor Using Compact Metamaterial UWB Antenna with a High Correlation Factor
The design of a compact metamaterial ultra-wideband (UWB) antenna with a goal towards application in microwave imaging systems for detecting unwanted cells in human tissue, such as in cases of breast cancer, heart failure and brain stroke detection is proposed. This proposed UWB antenna is made of four metamaterial unit cells, where each cell is an integration of a modified split ring resonator...
متن کاملA Planar, Layered Ultra-wideband Metamaterial Absorber for Microwave Frequencies
In this paper, an ultra-wideband metamaterial absorber is designed and simulated. The proposed absorber is planar and low profile. It is made of a copper sheet coated with two dielectric layers. Each unit cell of the metamaterial structure is composed of multiple metallic split rings, which are patterned on the top and middle boundaries of the dielectrics. The designed absorber utilizes differe...
متن کاملPerformance Enhancement of Microwave Sub-Wavelength Imaging and Lens-Type DOA Estimation Systems by Using Signal Processing Techniques
In this work, we show how we can improve the image resolution capabilities of a Phase Conjugating (PC) lens as well as the angular resolution of Luneburg lens antennas by employing signal processing techniques such as the Correlation Method (CM), the Minimum Residual Power Search Method (MRPSM), the sparse reconstruction method, and the Singular-Value-Decomposition (SVD)based basis matrix metho...
