He, Y. (author), Aubry, P. (author), Le Chevalier, F. (author), Yarovoy, A. (author)A new approach is proposed to extract the slow-time feature of human motion in high-resolution radars. The approach is based on the self-similarity matrix (SSM) of the radar signals. The Mutual Information is used as a measure of similarity. The SSMs of different radar signals (high-resolution range profile, micro-Doppler, and range-Doppler...journal article 2014

Babur, G. (author), Aubry, P. (author), Le Chevalier, F. (author)This paper describes a concept of the circulating codes covering the whole class of the space-time codes. The circulating codes do not narrow the radiated pattern of the antenna array, thus providing a wide angular coverage, possibly tunable. In turn, the beam-forming on transmit is achievable by means of the signal processing in one (or each)...journal article 2013

Tran, D. (author), Haider, N. (author), Aubry, P. (author), Szilagyi, A. (author), Lager, I.E. (author), Yarovoy, A. (author), Ligthart, L.P. (author)The number of topside shipboard antennas doubled every decade; in 1990s they were close to 200 and have no sight of stop growing (Tavik, 2005). The over-crowded present of such many topside antennas in a limited-space of littoral warfare ship has created/caused many critical, unavoidable problem like antenna blockage, electromagnetic...book chapter 2011

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
