Spatial Spectrum-Based Imaging for UWB Through-the-Wall MIMO Arrays

A Wall-clutter Suppression Method Based on Spatial Signature in Mimo Through-the- Wall Radar Imaging

In through-the-wall radar imaging (TWRI), wall returns are often stronger than target returns, which make the targets behind walls invisible in the radar image. Spatial filtering that relies on the removal of the spatial zero-frequency components is a useful way for wall-clutter mitigation. Unfortunately, it applies to through-the-wall radar (TWR) with synthetic aperture array only. In this pap...

Through Wall Imaging with Uwb Radar System

" If we save even one life, we have been cost effective. " Dr. Rochelle Dicker Acknowledgement I give a sincere gratitude to all the people who made it possible for me to write this thesis, especially to my family. I also want to thank to the doc. Ing. Miloš Drutarovsk´y, CSc. for my supervising, to the Dr. Jürgen Sachs and Dr. Rudolf Zetik for their technical and theoretical suggestions and re...

UWB Impulse Radar for Through-The-Wall Imaging

Ultra-Wideband (UWB) is the promising technology for localization of the objects behind the walls. Recent terrorist activities and law-enforcement situations underscore the need for effective through-wall detection. UWB radar signals has extremely large frequency spectrum and since low frequencies has more penetration capabilities through dielectric materials it is best suitable for Through-the...

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...
