• The Australian Defence Science and Technology Group (DSTG) has an appreciable heritage in applied radar research and development (R&D), perhaps most notably in High Frequency Over-the-Horizon Radar (OTHR).

    Significant experimental capabilities have also been developed by DSTG in microwave Active Electronically Scanned Array (AESA) radar, passive radar, synthetic aperture radar and real-time integrated sensing.

    This talk introduces selected examples of DSTG's radar capabilities, including some past and present initiatives and achievements.

  • Autonomous vehicles demand more precise and higher-resolution probabilistic environment models compared to traditional driver assistance systems. This talk explores how radar sensor technology can meet these requirements, with a focus on multi-sensor concepts and advanced signal processing techniques. The presentation highlights high-resolution grid mapping methods and probabilistic automotive SAR approaches, leveraging standard sensor hardware.

  • This talk outlines our synthetic-aperture approach to passive source localization and addresses a number of related issues.   For narrow-aperture collection geometries, we provide geometry-dependent resolution formulas that turn out to be very similar to the resolution formulas for (active) synthetic-aperture radar. 

  • The concept of radar has be intertwined with radio frequency communications it was first conceived. Hertz, Marconi, Hülsmeyer and others all observed the reflection of electromagnetic waves from objects around the end of the 19th and start of the 20th century, and early radio communications equipment was involved in the earliest observations. Interest in their interplay experienced a huge boost with DARPA’s Shared Spectrum Access for Radar and Communications (SSPARC) program started by Dr John Chapin in the early 2010s. The talk will discuss the radar-communications relationship from the earliest days through to recent advances and insights.

  • Since its inception at the dawn of the space age, the National Reconnaissance Office has been at the forefront of innovation.  Pioneering, in partnership with commercial industry, many of the firsts in space-based intelligence, surveillance, and reconnaissance to include Quill, the first radar imaging satellite in December 1964.  Today, the NRO is developing the most capable, diverse, and resilient overhead architecture in its history and commercial capabilities play a key role.  Commercial and national systems complement one another and allow NRO to satisfy a larger and broader set of requirements from across the user community, from the Department of Defense to the Intelligence Community to federal civil missions.   This includes commercial space-based radar capabilities.  NRO has been at the forefront of partnering with this industry from initial study contracts to operational use across the globe to leverage the capabilities and innovation being developed in the commercial market to enhance U.S. National Security.
