In this paper, the probefed stacked patch antenna and the E-shaped patch with a parasitically coupled selfcomplementary element (ESCE) are designed and analyzed in wall proximity in order to study the effects of various wall parameters on the antenna’s radiation characteristics. In particular, the effect of different wall-antenna separations as well as different wall material properties on impe...

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...

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...
