Improved Threat Detection in Walk-Through Security Scanning Using an Optimized Polarimetric Target Decomposition Method

open access: yesIEEE Journal of Microwaves, 2023
Reliable and convenient walk-through security scanning, which doesn't separate people or impede their movement, is an extremely challenging task. In this paper, a novel approach for a security check with an overhead observation and a polarimetric ...

Applying Polarimetric Target Decomposition to 2D Turntable ISAR Imagery of a Complex Vehicle

open access: yesInternational Journal of Antennas and Propagation, 2022
The capabilities of polarimetric target decomposition in SAR-based ATR applications are investigated by using 2D turntable ISAR imagery of a T-72 tank. To characterize target’s anisotropic scattering properties, wide-angle case is considered through the ...

Iterative PolInSAR Target Decomposition for Scattering Characterization and Building Detection

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In densely rotated built-up areas, restricted by interactive and complex scatterings, most polarimetric synthetic aperture radar scattering analyses and unsupervised building detection algorithms have failed, especially under conditions of large radar ...

Compact Polarimetric SAR Interferometry Target Decomposition With the Freeman–Durden Method

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
In this paper, we apply the Freeman–Durden decomposition method to the compact polarimetric synthetic aperture radar (SAR) interferometry (C-PolInSAR) data. The complex cross-correlation matrix of the single-baseline C-PolInSAR is decomposed into three $2\times 2$ covariance matrices, which correspond to the surface, the dihedral and the volume ...

Performance of SAR Polarimetric Calibration Using Hybrid Corner Reflectors: Numerical Simulations and Experimental Measurements

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
In this article, we devise a polarimetric calibration method utilizing only three types of calibration targets, i.e., trihedral, dihedral, and a 22.5°-rotated dihedral corner reflectors and requiring no assumptions on the scene statistics.

Polarimetric Decomposition With an Urban Area Descriptor for Compact Polarimetric SAR Data

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The compact polarimetric (CP) synthetic aperture radar (SAR) can alleviate the drawbacks of the fully polarimetric (FP) SAR and provide more target information as compared to the conventional single polarimetric and dual polarimetric mode.
