Current state-of-the-art in global positioning system (GPS) anti-jam technology has relied on a phase array antenna that consists of N antenna elements and a processing unit that performs a phase-destructive sum of any intentional and unintentional jamming up to N-1 signals. If this limitation is exceeded, then the GPS signal will degrade rapidly and become buried in the noise. Hence, alternative anti-jamming technologies have been sought recently. This talk describes an anti-jam method that can suppress more than N-1 jamming signals with a significant reduction in size, weight, and power (SWaP) and no degradation under additive white Gaussian noise (AWGN).
Hyuck M. Kwon received the B.S. and M.S. degrees in electrical engineering from Seoul National University, Seoul, Korea, in 1978 and 1980, respectively, and the Ph.D. degree in computer, information, and control engineering from the University of Michigan, Ann Arbor, MI, USA, in 1984. From 1985 to 1989, he was an Assistant Professor with the Department of Electrical Engineering and Computer Science, University of Wisconsin, Milwaukee, WI, USA. From 1989 to 1993, he was a Principal Engineer with Lockheed Engineering and Sciences Company, Houston, TX, USA, working on the National Aeronautics and Space Ad- ministration space shuttle and space station satellite communication systems. Since 1993, he has been with the Department of Electrical Engineering and Computer Science, Wichita State University, Wichita, KS, USA, where he is currently a Full Professor. In addition, he has held several visiting and consulting positions in communication system industries, a Visiting Associate Professor position with Texas A&M University, College Station, TX, USA, in 1997; a Visiting Professor position with the Korea Advanced Institute of Science and Technology, Daejeon, Korea, in 2005 and 2012; George Mason University, Fairfax, Virginia in 2017; and an Air Force Summer Faculty Fellow with the Air Force Research Laboratory, Kirtland Air Force Base, Albuquerque, NM, USA, in the summers of 2014, 2015, 2016, and 2018. His current research interests include wireless, massive multiple-input–multiple-output, cooperative, code-division multiple-access, and frequency-hopping spread-spectrum satellite communication systems.
