Presentation Abstract
This talk discusses the issues related to information extraction and data fusion from multiple sensors. The goal of extracting the maximum possible amount of information from each sensor requires the use of appropriate sensor and target models. In these models one has to quantify the corresponding uncertainties. The fusion of the information from the various sources has to account for their uncertainties as well as the interrelationship — crosscorrelations — between the various uncertainties across sources.
The four configurations for tracking with data fusion from multiple sensors are discussed with emphasis on Configuration II — Track-to-Track Fusion (T2TF). The existence of crosscorrelation of track errors across independent sensors is brought up and its impact is evaluated. The architectures of T2TF — with and without memory, with and without feedback — are discussed in detail. The surprising impact of feedback on the simplest T2TF (without memory) is explained. Finally, recent results on T2TF from heterogeneous sensors (active and passive) are presented.

Speaker Bio
Yaakov Bar­Shalom was born on May 11, 1941. He received the B.S. and M.S. degrees from the Technion, Israel Institute of Technology, in 1963 and 1967 and the Ph.D. degree from Princeton University in 1970, all in electrical engineering. From 1970 to 1976 he was with Systems Control, Inc., Palo Alto, California. Currently he is Board of Trustees Distinguished Professor in the Dept. of Electrical and Computer Engineering and Marianne E. Klewin Professor in Engineering at the University of Connecticut. He is also Director of the ESP (Estimation and Signal Processing) Lab. His current research interests are in estimation theory, target tracking and data fusion. He has published over 400 papers and book chapters in these areas and in stochastic adaptive control. He coauthored the monograph Tracking and Data Association (Academic Press, 1988), the graduate texts Estimation and Tracking: Principles, Techniques and Software (Artech House, 1993), Estimation with Applications to Tracking and Navigation: Algorithms and Software for Information Extraction (Wiley, 2001), the advanced graduate texts Multitarget­Multisensor Tracking: Principles and Techniques (YBS Publishing, 1995), Tracking and Data Fusion (YBS Publishing, 2011), and edited the books Multitarget­Multisensor Tracking: Applications and Advances (Artech House, Vol. I, 1990; Vol. II, 1992; Vol. III, 2000).

He has been elected Fellow of IEEE for “contributions to the theory of stochastic systems and of multi­target tracking”. He has been consulting to numerous companies and government agencies, and originated the series of Multitarget­Multisensor Tracking short courses offered via UCLA Extension, at Government Laboratories, private companies and overseas. During 1976 and 1977 he served as Associate Editor of the IEEE Transactions on Automatic Control and from 1978 to 1981 as Associate Editor of Automatica. He was Program Chairman of the 1982 American Control Conference, General Chairman of the 1985 ACC, and Co­Chairman of the 1989 IEEE International Conference on Control and Applications. During 1983­87 he served as Chairman of the Conference Activities Board of the IEEE Control Systems Society and during 1987­89 was a member of the Board of Governors of the IEEE CSS. He was a member of the Board of Directors of the International Society of Information Fusion (1999–2004) and served as General Chairman of FUSION 2000, President of ISIF in 2000 and 2002 andVice President for Publications in 2004-11. In 1987 he received the IEEE CSS Distinguished Member Award. Since 1995 he is a Distinguished Lecturer of the IEEE AESS and has given numerous keynote addresses at major national and international conferences. He is co­recipient of the M. Barry Carlton Award for the best paper in the IEEE Transactions on Aerospace and Electronic Systems in 1995 and 2000 and recipient of the 1998 University of Connecticut AAUP Excellence Award for Research. In 2002 he received the J. Mignona Data Fusion Award from the DoD JDL Data Fusion Group. He is a member of the Connecticut Academy of Science and Engineering. In 2008 he was awarded the IEEE Dennis J. Picard Medal for Radar Technologies and Applications, and in 2012 the Connecticut Medal of Technology. He has been listed by academic.research.microsoft (top authors in engineering) as #1 among the researchers in Aerospace Engineering based on the citations of his work.
