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...
متن کاملUWB Radar: Vision through a wall
There exist a lot of methods for vision through an opaque medium. At present UWB (Ultra-Wideband) technology is used more and more because it is suitable for localization and detection of a human body behind a wall. First of all this paper describes known methods for vision through walls, which can be divided into two general groups imaging and non-imaging systems. Secondly it describes the sta...
متن کاملDetection of Multiple Stationary Humans Using UWB MIMO Radar
Remarkable progress has been achieved in the detection of single stationary human. However, restricted by the mutual interference of multiple humans (e.g., strong sidelobes of the torsos and the shadow effect), detection and localization of the multiple stationary humans remains a huge challenge. In this paper, ultra-wideband (UWB) multiple-input and multiple-output (MIMO) radar is exploited to...
متن کاملDesign of a Compact Tapered Slot Vivaldi Antenna Array for See Through Concrete Wall UWB Applications
An optimized 1×8 Vivaldi antenna array designed for the lower-band UWB (2-4 GHz) through-wall imaging systems has been developed. Tapered slot antennas were utilized as the array elements and optimized to have a compact size. A one to eight wideband Wilkinson power divider was designed and fabricated to compose the feed network for Vivaldi antenna array. Measured results of the manufactured Viv...
متن کاملUWB 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...
