Through - 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...
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 کاملGeneral MIMO Framework for Multipath Exploitation in Through-the-Wall Radar Imaging
Detection and localization of stationary and moving targets within a building or an enclosed structure are highly desirable in through-the-wall radar imaging (TWRI) and urban sensing applications. These objectives are primarily challenged by two factors. First, multipath propagation of the electromagnetic waves gives rise to ghost targets [1]. Second, the need for highly resolved images results...
متن کاملMultipath Propagation of UWB Through-Wall Radar and EMC Phenomena
The UWB (ultra wide band) radar output signals can be substantially affected due to electromagnetic wave propagation through obstacles (such as walls) and multipath effects, too. Multipath effects are analyzed and simulated numerically for various cases with several antenna heights and distances. Delays (due to propagation through walls and various paths of direct and reflected rays) and the ri...
