Savelyev, T. (author), Zhuge, X. (author), Yang, B. (author), Aubry, P. (author), Yarovoy, A. (author), Ligthart, L. (author), Levitas, B. (author)This paper presents an experimental investigation of two approaches to short-range radar imaging at microwaves by means of ultra-wideband (UWB) technology. The first approach represents a classical synthetic aperture radar (SAR) that employs a transmit–receive antenna pair on mechanical scanner. The second one makes use of a multiple input...journal article 2010

Tanyer-Tigrek, F.M. (author), Tran, D.P. (author), Lager, I.E. (author), Ligthart, L.P. (author)An optimized coplanar waveguide fed quasimagnetic printed antenna for ultra wideband applications is described. A parameter study, motivated by a design procedure, allowed a substantial increase in the return-loss operational bandwidth. The numerically predicted performance was validated by means of physical measurements of fabricated samples....journal article 2009

Savelyev, T.G. (author), Yarovoy, A.G. (author), Ligthart, L.P. (author)This paper presents a 3-D imaging technique for an ultra-wideband (UWB) ground penetrating radar (GPR) with a single transmit antenna and a linear receive array. The video impulse GPR working in the frequency band of 0.3–3 GHz has been designed in IRCTR for landmine detection, i.e., for a near-field application. Installed on a vehicle it can...journal article 2008
