Compressive sensing for through-the-wall radar imaging
Through-the-Wall Radar imaging (TWRI) is emerging as a viable technology for providing high quality imagery of enclosed structures. TWRI makes use of electromagnetic waves to penetrate through building wall materials. Due to the " see " through ability, TWRI has attracted much attention in the last decade and has found a variety of important civilian and military applications. Signal processing...
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...
متن کاملInteraction Multipath in Through-the-Wall Radar Imaging Based on Compressive Sensing
Clutters caused by multipath have been widely researched in through-the-wall radar imaging (TWRI). The existing research work of multipath only consider reflections from the wall, while in the condition of a small scene, with the increasing number of targets, multipath from targets to targets, named interaction multipath, usually generates ghosts, which degrades the performance of TWRI. In orde...
متن کاملStudy of Compressive Sensing on through Wall Imaging
The theory of Compressive Sensing (CS) enables the reconstruction of sparse signals as well as image from small set of random measurements by solving primal dual interior point method for l1 minimization problem. This paper presents reconstruction of signal based on CS theory applied on experimental data. Reconstruction of Ascan and B-scan image with fewer samples is obtained without affecting ...
متن کاملThrough - Wall Imaging Radar
Knock and announce missions occur frequently on the urban battlefield. It would be advantageous to locate all of the humans inside an urban structure and obtain a "head count" prior to action. For this reason, we developed a through-wall radar sensor capable of locating moving targets through concrete-walled structures and of displaying the results (in range versus cross range) at a video frame...
