Ruyu Ma, a PhD student in the Department of Electrical and Computer Engineering at UW-Madison, won second place in the USNC/CNC URSI student paper competition held during the online 2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting in early July 2020.
Ma is currently a research assistant in the lab of McFarland-Bascom Professor of Electrical and Computer Engineering Nader Behdad.
His winning paper, entitled “A Spatially-Confined, Platform-Based HF Direction Finding Array,” discusses a new technique for radio direction finding, an application that is used in navigation, radar, reconnaissance and advanced communication systems. The paper demonstrates a new way to exploit inherent radiation modes of platforms like automobiles and aircraft to enhance high-frequency, small-aperture direction finding systems. Typically, the accuracy of these onboard direction-finding antennas is capped by fundamental physical and statistical limits.
