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 کاملCompressive 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 کاملTwo-dimensional Diffraction Tomographic Algorithm for Through-the-wall Radar Imaging
In this paper, a two-dimensional (2D) diffraction tomographic algorithm based on the first order Born approximation is proposed for the imaging of hidden targets behind the wall. The spectral expansion of the three layered background medium Green’s function is employed to derive a linear relationship between the spatial Fourier transforms of the image and the received scattered field. Then the ...
