«In this seminar, organised in partnership by ISR-Lisboa, Nanosatlab, and IDMEC, Keith LeGrand will share his experience in “Cislunar Space Domain Awareness and Information-Theoretic Multi-Object Surveillance”.

Keith LeGrand is an Assistant Professor of Aeronautics and Astronautics and director of the Sensing, Controls, and Probabilistic Estimation (SCOPE) group at Purdue University. LeGrand received his Ph.D. in Aerospace Engineering from Cornell University and was a Senior Member of Technical Staff at Sandia National Laboratories in Albuquerque, New Mexico, where he conducted research in inertial navigation, space systems, and multi-object tracking. LeGrand received his M.Sc. in Aerospace Engineering from the Missouri University of Science and Technology and is the recipient of the International Society of Information Fusion (ISIF) Young Investigator Award and the United States Air Force Office of Scientific Research (AFOSR) Young Investigator Program Award. His research interests include nonlinear estimation, multi-sensor multi-object tracking, and space domain awareness.

This talk will discuss recent advances in nonlinear and non-Gaussian state estimation, with applications to tracking and manoeuvring objects in chaotic dynamical systems. Additionally, this talk will discuss the search-while-tracking (SWT) problem and present a generalised approach to information-driven sensor tasking. The proposed approach considers the impact of non-Gaussian kinematic uncertainty, unknown target existence, data association uncertainty, and target appearance/disappearance.»
