Baladi, Elham (author), Xu, M. (author), Faria, Nicolas (author), Nicholls, Jeff (author), Hum, Sean V. (author)This work presents the design and experimental validation of a dual-band fully reconfigurable circularly polarized (CP) reflectarray (RA) antenna for satellite communication applications in the Ku-band. The proposed structure operates with the downlink and uplink beams at frequency bands of [10.8-11.8] and [14-15.4] GHz, respectively....journal article 2021

Xu, S. (author), Yarovoy, Alexander (author)This article addresses the joint estimation of range, velocity and azimuth for multiple fast-moving targets using (ultra-)wideband (UWB) frequency-modulated continuous-wave (FMCW) radar with a phased array in the presence of Doppler ambiguities. The range migration of moving targets is described with the coupling of the fast-time and slow...journal article 2020
