Journal ArticleDOI
Refocusing Through Building Walls Using Synthetic Aperture Radar
TL;DR: Through-wall imaging/sensing using a synthetic aperture array technique is studied by employing ultrawideband antennas and for wide incidence angles and a dual-frequency synthetic method is presented that can improve the cross-range resolution of the refocused image.
Journal ArticleDOI
Through-the-Wall Imaging Using Differential SAR
TL;DR: An algorithm for imaging of targets behind walls is proposed to reduce the wall reflection and enhance the signal-to-clutter ratio and, in this approach, specular reflections are totally eliminated without the need for the knowledge of the wall parameters.
Journal ArticleDOI
A Printed Circularly Polarized Y-Shaped Monopole Antenna
A. Ghobadi,Mojtaba Dehmollaian +1 more
TL;DR: In this paper, a printed circularly polarized omnidirectional Y-shaped monopole antenna for possible satellite and terrestrial applications is presented, which incorporates the desirable features of wire turnstile antennas while eliminating external coupler networks used in those antennas.
Journal ArticleDOI
Wave Scattering by a Cylindrical Metasurface Cavity of Arbitrary Cross Section: Theory and Applications
TL;DR: In this article, the authors presented compact, insightful, and convenient formulas to compute the scattering of electromagnetic waves by cylindrical metasurfaces, forming 2D porous cavities of arbitrary cross section.
Journal ArticleDOI
Electromagnetic Scattering From Foliage Camouflaged Complex Targets
TL;DR: A hybrid target-foliage model based on existing electromagnetic techniques is developed to investigate the scattering behavior of hard targets embedded inside a forest canopy at high frequencies using a coherent discrete scattering model that makes use of realistic tree structures.
