Dr. Gupta received his BS (Electronics and Electrical Communication) from Punjab University, India, in 1975, his MS (EE) from the Indian Institute of Technology, Kanpur; India in 1977 and his Ph.D. from The Ohio State University in 1982. Since 1979 he has been with the Department of Electrical and Computer Engineering of The Ohio State University. He currently holds the title of Professor Emeritus and is actively pursuing his research interests. He is a Fellow of the IEEE, a Fellow of the Institute of navigation (ION), and an Edmond S. Gillespie Fellow of the Antenna Measurement Techniques Association (AMTA). He is the recipient of 2007 AMTA Distinguished Achievement Award. He has also received The Ohio State University College of Engineering Lumley Research Award for 1991, 1998, 2005 and 2011. Most recently, he received Captain P.V.H. Weems Award from the Institute of Navigation for his continuous contributions to the art and science of navigation.
Dr. Gupta’s research interests include radar imaging, EM scattering, compact range technology, array signal processing (adaptive antennas and emitter geo-location), and target identification. He has developed various techniques for enhancing the quality and resolution of radar images, including AR modeling, maximum likelihood estimation and data extrapolation. He has designed state-of-the-art reflectors for compact range measurement systems, as well as techniques to evaluate the performance of antenna and radar test ranges. He has worked extensively on adaptive antenna arrays for radio frequency interference suppression and multipath mitigation in communication systems and navigation systems. Currently, he is working on GPS antennas and antenna electronics, and radio frequency emitter geo-location.
