Abstract:

Advances in radio frequency (RF) solid state transmitters and high performance embedded computing (HPEC) have afforded a new opportunity to “re-write” the textbooks on active sensing systems such as radar. Previously, radars were constrained to pre-determined set of transmit waveforms such as linear frequency modulation (LFM), and pseudo-random binary modulation with constant modulus. It is now possible to utilize advanced arbitrary waveform generators (AWGs) that are also adaptive. In this talk we will develop from first principles the theory of optimal and adaptive waveform design. We will see that to achieve optimality, knowledge of the entire multidimensional radar channel is required. Performance bounds for optimal detection and target ID are presented along with illustrative applications. The talk concludes with areas of ongoing and future research [1-5].

Speaker Bio:
Dr. Guerci has over 30 years of experience in advanced technology research and development in government, industrial, and academic settings. His government service included a 7-year term with the Defense Advanced Research Projects Agency (DARPA) in which he held the positions of Program Manager, Deputy Office Director, and finally Director of the Special Projects Office (SPO). In these capacities, Dr. Guerci was involved in the inception, research, development, execution, and ultimately transition of next generation multidisciplinary technologies. He is currently President and CEO of Information Systems Laboratories, Inc. Dr. Guerci is a recognized leader in the research and development of next generation sensor and communication systems. In addition to authoring over 100 peer reviewed articles, he is the author of several popular books including Space-Time Adaptive Processing for Radar (Artech House, 2003, 2nd Ed. 2014), and the recently published Cognitive Radar, (Artech House, 2010). Dr. Guerci is the recipient of the Warren D. White Award from the Institute of Electrical and Electronics Engineers (IEEE) for “Excellence in Radar Adaptive Processing and Waveform Diversity”, and is a Fellow of the IEEE for “Contributions to Advanced Radar Theory and its Embodiment in Real-World Systems”. He has also recently been appointed the General Chair for the 2015 IEEE International Radar Conference, and been selected to serve as Associate Editor for the IEEE Transactions on Signal Processing, and as the Radar Series Editor for Artech House publishers. A graduate of NYU Polytechnic Institute with a PhDEE (now NYU Tanden School of Engineering), Dr. Guerci has held adjunct professorships in engineering and applied mathematics at The City University of New York, NYU Polytechnic University, The Cooper Union for Advancement of Art and Science, and Virginia Tech. Additionally, he has held senior engineer and scientist positions in industry and was Chief Technology Officer (CTO) for SAIC’s $2B+/year Research, Development, Test & Evaluation (RDT&E) Group, and is currently a member of several industrial, academic, and government advisory boards.
