2023 AESS Virtual Distinguished Lecturer Series: Luke Rosenberg - 3D ISAR: Techniques and Applications
In maritime radar, Inverse Synthetic Aperture Radar (ISAR) is used to image targets with classification typically performed by a radar operator. Three dimensional (3D)-ISAR was developed as an alternative representation with the target represented by a 3D point cloud, instead of the traditional range/Doppler image. This provides extra spatial information that can be exploited for automatic target recognition.
There are three algorithms that can have been developed depending on the receiving system’s configuration: a temporal-based approach that uses a single receiver, a dual-baseline interferometric-ISAR (InISAR) with 3 receivers and a hybrid temporal-InISAR approach that uses 2 receivers along a single (horizontal) baseline that is suitable for airborne maritime surveillance platforms. To attain robust 3D-ISAR based target classification, our research has explored techniques for improving the quality of point cloud imaging using polarimetric-ISAR, array ISAR and sea clutter suppression. This talk will describe each of these enhancements and demonstrate how the improved localisation can be used to enhance target classification.

Biography:
Luke Rosenberg received the Bachelor degree in electrical and electronic engineering, a Masters degree in signal and information processing, and the PhD degree from the University of Adelaide, Australia. In 2016, he completed the Graduate Program in Scientific Leadership at the University of Melbourne. He is currently an adjunct Associate Professor with the University of Adelaide and a Senior Research Engineer at STELaRLab, Lockheed Martin Australia. Prior to this he worked at the Defence Science and Technology Group Australia as a research specialist in maritime radar and in 2014, he spent 12 months with the U.S. Naval Research Laboratory (NRL) working on algorithms for focusing moving scatterers in synthetic aperture radar imagery. His work covers the areas of radar image formation, classification, adaptive filtering, detection theory, and radar and clutter modelling. Dr. Rosenberg has received a number of best paper awards, the prestigious Defence Science and Technology Achievement Award for Science and Engineering Excellence in 2016 and the IEEE AESS Fred Nathanson award in 2018 for ‘Fundamental Experimental and Theoretical Work in Characterizing Radar Sea Clutter’. He is a member of the AESS board of governors and radar systems panel, a distinguished lecturer for the AESS, senior editor for the Transactions of Aerospace and Electronic Systems and past chair of the IEEE South Australian Section. He has over 170 publications including a recent book: Radar Sea Clutter: Modelling and Detection.
