Frequency-Modulated Interrupted Continuous Wave as Wall Removal Technique in Through-the-Wall Imaging

Dual Channel S-Band Frequency Modulated Continuous Wave Through-Wall Radar Imaging

This article deals with the development of a dual channel S-Band frequency-modulated continuous wave (FMCW) system for a through-the-wall imaging (TWRI) system. Most existing TWRI systems using FMCW were developed for synthetic aperture radar (SAR) which has many drawbacks such as the need for several antenna elements and movement of the system. Our implemented TWRI system comprises a transmitt...

Durham E-Theses Through-The-Wall Detection Using Ultra Wide Band Frequency Modulated Interrupted Continuous Wave Signals

Robotic Through-Wall Imaging

The overall goal of this paper is to present the new possibilities created at the intersection of robotic path planning and inverse scattering for through-wall imaging with everyday RF signals. More specifically, we are interested in the throughwall imaging of a completely unknown space using unmanned vehicles and with everyday RF transceivers. We first focus on robotic through-wall imaging bas...

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...

Domain wall propagation through spin wave emission.

We theoretically study field-induced domain wall motion in an electrically insulating ferromagnet with hard- and easy-axis anisotropies. Domain walls can propagate along a dissipationless wire through spin wave emission locked into the known soliton velocity at low fields. In the presence of damping, the usual Walker rigid-body propagation mode can become unstable for a magnetic field smaller t...
