Randall Summers is a masters student in the School of Electrical and Computer Engineering, advised by Dr. Mark Yeary. Randall's current research investigates the impact of various predistortion algorithms on the performance of radar systems. Randall said, "I'm also looking into beam-shaping algorithms for phased arrays and ways to quickly evaluate super-resolution algorithms.
