Abstract

Inverse synthetic aperture radar (ISAR) has been developed to image non-cooperative targets, so they can be classified by an operator or a more advanced classification system. Three dimensional (3D) ISAR is an extension that produces a different target representation designed to improve the classification results. The technique works by estimating the target scatterers’ position using measurements from multiple ISAR images. This has previously been achieved using a single receive channel that exploits the temporal motion of the target or with a multichannel dual-baseline interferometric system that uses the phase differences in both the along and across track directions. In our current project, we propose a combination of these two techniques using a single along track baseline suitable for airborne maritime radar systems. The techniques using both the single and dual-baseline configurations were applied on the simulated data and real data captured from the Livorno’s experiment (NATO-196) to investigate their performance for scatterers’ positions and dimension estimations.

Biography

Chow Yii Pui received his B Eng. (Hons) degree (Electrical and Electronic) and PhD. degree from the University of Adelaide, Australia in 2009 and 2017 respectively. He worked on projects involved with search and rescue downlink signals tracking using a phased array receiver, LTE based passive bistatic radar and DVB-S2 based passive inverse synthetic aperture radar (ISAR) at the University of South Australia. He is currently working on a DSTG sponsored 3D-ISAR project at the University of Adelaide. His research interests include passive bistatic radar, phased array and ISAR.
