Detection in the maritime domain requires the radar return from targets to be distinguishable from the background interference. These radars traditionally use non-coherent processing due to the time-varying and range-varying nature of the Doppler spectra. However, as radar platforms fly higher and look down at steeper angles, the sea clutter power will increase and traditional methods will not be as effective.
This talk covers three new approaches for target detection in the maritime domain. These include the use of stationary wavelet transforms to isolate different spectral features, the use of sparse signal separation algorithms and the application of the single snapshot coherent detector. Each of these techniques is demonstrated using using either real or realistic simulated sea clutter and shows good potential when compared to traditional non-coherent processing methods.
About the speaker:
Dr. Luke Rosenberg received his Bachelor of Electrical and Electronic Engineering in 1999, Masters in Signal and Information Processing in 2001 and Ph.D. in 2007, all from the University of Adelaide, Australia. In 2016, he received his Graduate Program in Scientific Leadership from the Universiy of Melbourne, Australia. He is currently the Science Team Lead for airborne maritime radar at the Defence Science and Technology (DST) Group, Australia and an adjunct Senior Lecturer at the University of Adelaide.
Dr. Rosenberg’s Ph.D. thesis proposed new multichannel radar image formation algorithms and looked at techniques for forming images while suppressing undesired interference in the main beam of a radar. From 2006 to 2011, he worked in the imaging radar group, where his work included radar image formation and the analysis and modelling of radar sea-clutter. In 2011, he moved into the maritime radar group where he also worked on radar performance prediction, target detection algorithms and radar imaging of non-cooperative targets. During 2012-2016, he was the Australian representative on the NATO SET-185 panel on high grazing angle sea-clutter and in 2014, spent 12 months at the U.S. Naval Research Laboratory (NRL) working on algorithms for focusing moving scatterers in synthetic aperture radar imagery. As the radar scientific lead for airborne maritime radar, he is responsible for delivering the work program for maritime target detection, radar modelling and simulation, electronic protection, maritime imaging techniques and automatic target recognition. In addition, Dr. Rosenberg is an active member of the Technical Cooperation Program (TTCP) TP-2 radar group.
Dr. Rosenberg has jointly authored more than 100 publications, has received a number of paper awards at international radar conferences and is a regular presenter of tutorials. In 2016, he received the prestigious Defence Science and Technology Achievement Award for Science and Engineering Excellence, in 2017 the NRL ARPAD award with colleagues from the NRL and in 2018, the IEEE AESS Fred Nathanson award for ‘fundamental experimental and theoretical work in characterising radar sea clutter.’ He is also a member of the radar systems panel, a senior member of the IEEE, an associate editor for the Transactions of Aerospace and Electronic Systems (AES) and is the vice chair of the IEEE South Australian section and the Control and AES chapter chair.
